Interesting project. I never thought there would be a possibility to get one of these given the rarity.

That's one of the reasons why I started this project.
On the other hand, emedia apparently still had ~40 bare PCBs in stock back in 2010 - along with a few PAK68/3-020 and PAK68/2 boards.

Sorry to raise an old thread, but I just wanted to remark that (even though I don't know what this is!) this kind of project is amazing, much respect for not just doing this, but also getting it open-sourced.

There are lots of DIY schematics of Atari hardware abound, but half of it gets lost on free hosting pages and, oh yeah back to my point, Eagle files of things ar what's needed to preserve or extend them to others. Oshpark.com makes it so easy for a newbie to get a small run of PCBs done, for not a lot of money, and it'd be awesome to see more products/mods preserved in Eagle.

To put it simple, I got kind of carried away.

Status is as follows:
PAK68/3-030A - finished, funding for a prototype has been semi-secured but I wanted to tripple-check everything before hand - expect this to be finished in the next 12 months at worst. One future problem will be the fact that the TAG-RAMs used are discontinued and very hard to obtain.
PAK68/3-020 - only scanned the PCB
PAK68/2 - started redrawing in EagleCAD, currently on hold
FRAK/2 - finished, no funding or plans for prototype yet - also, this one will probably get a new revision, incorporating all fixes mentioned in the manual and possibly will become a 4 layer board to improve power distribution.
PuPla/2 - finished but needs some cleanup in EagleCAD, schematics are currently being made by Artur from KiCAD
Panther/2 - never recieved the empty PCBs I ordered :( Artur from atari-area (polish forum) has redrawn the PCBs in KiCAD

exxos: mind giving me a quote for a 4-layer board? roughly 180x120mm - the high price of ~100€ for a prototype is kinda making me hesistate until i'm sure absolutely everything is correct.

One small step for this forum, one giant leap for the project!
As a minor posting for now, atari-forum has been decided as the definite source for updates on this project. What was previously spread chaotically over multiple forums in different languages has now been streamlined.

As a first update I'll be posting an extensive summary of the current progress, rephrasing my target for this project, a future outlook as well as clearing up some loose ends which may have been unclear/misunderstood in the past.
For now I just have the current progress of the individual subprojects inside the PAK line ready in German, but will provide the forum with the promised full post soon (might take a few days - since I will be visiting my sister who has made me an uncle last sunday :)).

General progress:
Gegenwärtig aktive Projekte:
PAK68/3-030A: Als Layout produktionsfertig und quasi funktionsfähig, allerdings möchte ich mein Layout vor einer Veröffentlichung mit dem vorhandenen Schaltplan aus der c't & den mir vorliegenden Update Notizen verknüpfen, so dass Fehler definitiv ausgeschlossen werden können und zukünftige Updates durch Dritte im Design leichter eingepflegt werden können.
FRAK/3: Momentan das Projekt mit der höchsten Priorität, Schaltplan der Version 3 und Layout auf Grundlage von Version 2 sind bereits miteinander verknüpft, noch nicht alle zusätzlichen Features sind im Layout abgebildet. Von der Vollständigkeit das bislang umfangreichste Projekt.


Gegenwärtig inaktive Projekte:
FRAK/2: Layout als "Replika"-Design vorhanden, kein Schaltplan, benötigt noch ein "Cleanup" da das Layout den DRC von Eagle nicht besteht. Veröffentlichung fraglich, da die FRAK/3 bereits weiter entwickelt und 99% kompatibel ist (die FRAK/3 ist auf Hardwarelevel zur PAK68/3-020 zusätzlich inkompatibel, da für die Kombination FRAK/2 und PAK68/3-020 nie GALs existiert haben und ein Update die Kapazitäten dieses Projekts sprengen würde).
PAK68/2: Es existiert ein Schaltplan welcher in der c't abgedruckt wurde, zusätzlich wurde die Platine von mir gescannt/abgeleuchtet. Teilweise bereits als Layout vorhanden, vorläufig aber "auf Eis", kann aber jeder Zeit wieder aufgenommen und fertiggestellt werden - eine Veröffentlichung ist langfristig geplant.
Panther/2: Mir liegen die originalen PCB Produktionsdateien, sowie ein Platinensatz vor - eine Portierung nach Eagle ist geplant allerdings niedrig priorisiert. Dieses Projekt habe ich noch nicht begonnen, da noch wenige Platinen zum Verkauf angeboten werden und ich die Platinen/PCB Files erst kürzlich erhalten habe. Ziel ist es neben der digitalen Archivierung der PCB Dateien den Schaltplan zu reversen/abzuleiten.
PuPla/2: Es existieren noch ca. 20 leere Boards, das Layout ist zu 90% in Eagle fertiggestellt - dieses Projekt hat gegenwärtig die geringste Priorität da noch ausreichend Platinen verfügbar sind. Ziel ist es neben der digitalen Archivierung der PCB Dateien den Schaltplan zu reversen/abzuleiten.


Sonstige Nebenprojekte:
Die Eagle Layouts für die PLCC-DIL 68k Löt- und SOJ-DIP300 TAGRAM Steckadapter, welche als Beiprodukte des Projekts am entstehen sind stelle ich an diesem Punkt "auf eigenes Risiko" zur privaten Nutzung und uneingeschränkten Verwertung bereit. Der CPU-Adapter ist ein ungetesteter Prototyp, das Design für den TAGRAM-Adapter befindet sich im frühen Entwurfsstadium und benötigt in dieser Form Nacharbeit.
http://www.file-upload.net/download-835 ... r.zip.html


Nicht unterstützte, aber mögliche, zukünftige Projekte:
Generation 3:
PAK68/3-030: Veraltete Revision ohne Mehrnutzen auf Kosten von Features, Schaltplan wurde in der c't abgedruckt.
PAK68/3-020: Veraltete Revision mit partiellem Mehrnutzen auf Kosten von Features. Schaltplan ist leicht von der abgedruckten 030er Variante ableitbar, es existieren Scans von der Platine. Mit geringem Aufwand sollte sich dieses Projekt später von den 030A Dateien ableiten lassen.
FRAK/1: Es existiert ein nicht-öffentlicher Schaltplan. Veraltete Revision ohne Mehrnutzen.
Panther/1: Veraltete Version ohne Mehrnutzen, wie ein Panther/2 ohne Netzwerkfunktionalität. Diese Boards scheinen auch nur in sehr begrenzten Stückzahlen zu existieren, Dokumentationen sind mir bis auf ein Foto keine bekannt.

Generation 2:
PuPla bzw. PAK-Puffer: Veraltete Revision ohne Mehrnutzen allerdings mit leichterem Aufbau, durch die ausschließliche Verwendung von DIP Bauteilen. Allerdings fehlen in dieser Version Features. Die PuPla/2 ersetzt diese völlig. Bis auf Fotos keine Dokumentationen vorhanden.
PuSTE: Ebenfalls veraltet und zusätzlich recht problemanfällig. Der Mehrgewinn zur PuPla(/2) ist durch den PLCC-DIL Lötadapter den ich als Nebenprojekt gelayoutet habe abgedeckt. Dokumentation nur als Fotos vorhanden.
PUK: Keine Dokumentationen vorhanden. Die Funktionalität ist auf der PAK68/3 bereits inbegriffen, fehlt aber bei der PAK68/2. Eventuell als zukünftiges Projekt denkbar.

Generation 1:
PAK-68: Es existiert ein Schaltplan welcher in der c't abgedruckt wurde. Eventuell als zukünftiges Projekt denkbar.
PAK-68 SRAM Daughterboard: Ein Schaltplan sollte in der c't abgedruckt worden sein. Allerdings ist die Existenz des Schaltplans ungewiss, da mir jenes Heft der c't nicht zur Verfügung steht. Eventuell als zukünftiges Projekt denkbar. Sonst nur in Form eines einzelnen Fotos dokumentiert.
FRAK/2 -> FRAK/3 specific changelog:
Aktuelle Änderungen:
- Alle Fixes der FRAK/2 sind bereits im Schaltplan/Layout berücksichtigt.
- Das Layout wurde auf ein 4-lagiges Design umgestellt (bessere Masse, mehr Übertaktungspotential).
- Die Adressleitungen haben ein kleines Brüderchen namens A11 erhalten.
- die Durchkontaktierungen der Datenleitungen und Sockel für die Treiberchips wurden so weit auseinandergelegt, dass die optionalen Terminatoren bequemer (und theoretisch sogar nachträglich) verlötet werden können (0805er SMD, 3 DIP Raster Platz dafür)
- Alle Jumper der PAK wurden durchkontaktiert, so dass ein auseinanderbauen des Turms entfällt (Optionen welche durch die Präsenz der FRAK festgelegt werden sind "hardwired") zusätzlich wird der Takt sauberer zwischen den Platinen weitergereicht.
- PAK/3-020 spezifische Bauteile wurden entfernt, da für diese Kombi nie GALs existiert haben und ich diese eh nicht als PCB Files digitalisieren wollte.
- Noch ein paar Kleinigkeiten mehr, die mir grade nicht einfallen wollen

Re: Project rePAK

Post by DarkLord »

Until your full post, I took the liberty of using "google translate" on what was here,
with the understanding that "google translate" is anything but perfect. :)

Currently active projects:

PAK68/3-030A: As the layout ready for production and quasi-functional, but I
want to link my layout before publication with the existing wiring diagram
from the c't & the present update my notes, so that errors can be definitely
ruled out and future updates by third parties can be more easily maintained
in the design.
FRAC / 3: The project is currently the highest priority, circuit diagram and
layout of the Version 3 based on version 2 are already linked, not all the
extra features are depicted in the layout. From the completeness of the most
extensive project.

Currently inactive projects :
FRAC / 2 : Layout available as a " replica " design, no wiring diagram ,
needs a " cleanup " because the layout of the DRC Eagle does not exist.
Publication is questionable as the FRAC / 3 already developed and 99 %
compatible ( the FRAC / 3 is at hardware level to PAK68/3-020 additional
incompatible, because never have existed GALs for the combination FRAC / 2
and PAK68/3-020 and an update would be beyond the capacity of this project )
.
PAK68 / 2 : There is a circuit diagram which was printed in the c't , in
addition, the board has been scanned / abgeleuchtet from me. Partial already
exists as a layout , but for the time being " on hold " , but each time can
be resumed and completed - a publication is planned in the long term .
Panther / 2: I have received the original PCB production files , as well as a
platinum record - a port to Eagle is however planned prioritized low. This
project I have not yet started because a few boards are up for sale and I
have recently received the boards / PCB files. The aim is next to the digital
archiving of the PCB files to derive the circuit diagram reverse / .
PuPla / 2 : There are about 20 blank boards, the layout is completed to 90%
in Eagle - This project currently has the lowest priority as yet sufficiently
boards are available . The aim is next to the digital archiving of the PCB
files to derive the circuit diagram reverse / .

Other side projects:
The Eagle layouts for PLCC-DIL 68k soldering and SOJ DIP300 TagRAM plug
adapters, which are produced as by-products of the project are I imagine at
this point "at your own risk" for private use and unlimited exploitation
ready. The CPU adapter is an untested prototype, the design for the TagRAM
adapter is in the early design stage and requires in this form rework.
http://www.file-upload.net/download-835 ... r.zip.html

Unsupported, but possible future projects:
Generation 3:
PAK68/3-030: Outdated revision at no extra benefit at the expense of features
circuit diagram was published in c't.
PAK68/3-020: Outdated revision with partial extra benefits at the expense of
features. Diagram is slightly different from the printed 030 variant derived,
there are scans of the board. With little effort, this project should be
later derived from the 030A files.
FRAC / 1: There exists a non-public schematic. Outdated revision at no extra
benefits.
Panther / 1: Obsolete version at no additional benefits, like a panther / 2
without network functionality. These boards seem to exist only in very
limited numbers, documentaries are not known to me except for a photo.

Generation 2:
PuPla or PAK-buffer: Outdated revision at no extra benefits but with a
lighter structure, through the exclusive use of DIP components. However, in
this version missing features. The PuPla / 2 replaces it completely. Up to
present no Photos documentation.
Breath: Also, outdated and in addition quite prone to problems. The more
profit for PuPla (/ 2) by the PLCC DIP Adapter series I've mockup as a side
project covered. Documentation available only as photos.
PUK: No documentation available. The functionality is on the PAK68 / 3
already included, but is absent in the PAK68 / 2 Possibly as a future project

Generation 1:
PAK-68: There is a circuit diagram which was printed in the c't. You may be
conceivable as a future project.
PAK-68 SRAM daughterboard: A circuit diagram should have been printed in the
c't. However, the existence of the circuit diagram is uncertain as to me that
issue of c't is not available. You may be conceivable as a future project.
Otherwise documented only in the form of a single photo.

RecentChanges:
- All fixes the FRAC / 2 are already taken into account in the schematic /
layout.
- The layout was on a 4 - layer design changed (improved mass , more
overclocking potential).
- The address lines have received a little brother named A11.
- The vias of the data lines and sockets for the driver chips were placed so
far apart that the optional terminators convenient ( and theoretically even
later ) can be soldered ( 0805er SMD, DIP 3 grid space for it )
- All jumper PAH were contacted so that a disassemble the tower is omitted (
options which are defined by the presence of the FRAC " hardwired " ) in
addition , the clock is clean passed between the boards .
- PAK/3-020 specific components have been removed because of this combination
never have existed GALs and I did not want this anyway digitize PCB files.
- Just a few more little things that just do not want to come to my (mind?).

PAK = "Prozossor Austausch Karte" ("processor replacement card").

A DIY project series of the German c't computer magazine to speedup 68k computers with 030, 020 ("PAK") and fastram boards ("FRAK") which was pretty popular at its time. They were manually layouted at their time and the design was lost (?) - Shockwav3 is working on a CAD based redesign/rebuild.

YAY for translations (this is a spacer, I'll edit this post as translations come in):

What are the PAK-68 / PAK68/2 / PAK68/3-030A and their related projects?
The PAK* line of addons are speeder cards for 68k based computers, by the german c't magazine designed as DIY projects with extensive documentation and discussion in their magazine. The full german name is "Prozessor Austausch Karte" which translates to "processor replacement/exchange card".
First started with the PAK-68 published in 1987, it later got a new revision as the PAK68/2 in 1991 and the current latest incarnation the PAK68/3 in 1993.
A special feature about this line of CPU speeders is, next to the ease of building them yourself, the fact that they can be used in Atari, Amiga and Mac (and possibly other) 68k computers due to the use of programable logic in the shape of GAL chips. Heise (the publisher of the c't magazine) always included full schematics and source codes along their articles regarding the PAK. Until late 2011 they even had some remaining stock for their produced circuit boards.
Later in their life they even became a base for additional addons, namely the PuPla (Puffer Platine / buffer board), the FRAK (FastRAM Austausch Karte / FastRAM replacement card) and the Panther (ISA based graphics and network adapter), published by either MW-Electronic or WRS.
So ... what's your take in this?
Seeing how these cards are still popular with Atari and Amiga users and all stock being long (or not so long) gone - along with them being really nifty DIY projects - I decided to revive them.
The current aim is to replicate the original circuit boards in a digital format (EagleCAD, Gerber) so anyone interested can produce their own at any time. Since this process is very manual (scanning empty PCBs, minor editing in Photoshop, redrawing all traces in Eagle) and prone to errors and could basically be skipped by using acetone and a good copy machine, the PCB layouts will be linked to the published schematics (or upgraded versions based on those). Bugfixes and some additional features will be included in the layouts, so replicating might be the wrong phrase, but you will still be able to see how they're related to their ancestors (meaning you won't see a PAK68/3-060, but will get rid of jumpwire fixes and the like). While this was originally started as a doodling around in Eagle, it has now become a full project, along with various contributors.
Wait, you're saying that you're making production files but no PCBs - does that even make sense?!
Yes and yes. The only PCBs I will produce myself will be prototypes to eliminate any mistakes which may have slipped in. While this might seem odd at first, it's intended to aid future developments based upon these projects so they don't have to reinvent the wheel. My experience with various retro communities has also given me very positive examples of users organising themselfes to have boards produced - or building upon non-physical projects. The SID-revectorization project by Tommi Lempinen and Michael Huth or the ULA book by Chris Smith are 2 prime examples I want to name here (check them out, even if you don't care about Commodore/Sinclar machines).
While producing & distributing PCBs myself and keeping the production files closed might give me one major advantage in the form of control over people trying to monetarize efforts by others as it has happened with the HxC (I'm not refering to HxC closing the source and moving production to Lotharek to prevent misunderstandings) and others I see free and available knowledge as the greater overall outcome (I guess my bonds to the punk scene are showing here :cheers:). The final license will have a paragraph on this - as I intended the project to allow private, non-commercial derivates as long as the original sources are referenced.
I will help finding a producer and distributor for a first batch of PCBs.

Following is a list of all PAK* related projects I'm aware of, as well as their current status in this project. Also included is a changelog for the FRAK/3 at the end.

Currently active projects:
PAK68/3-030A: The layout is done and basically ready for production, but before a prototype and a later release I wanted to link my layout to the printed schematics and upgrade notes, so I can be as sure as possible that no errors have slipped in. This way future upgrades on the design can be intregrated easier too.
FRAK/3: Currently the project with the highest priority. Schematic of version 3 and an upgraded layout based upon version 2 are linked together, but not everything is done yet. In the sense of completeness this is so far the biggest project.
Currently inactive projects:
FRAK/2: Layout exists as a "replica"-design, which currently fails the DRC of eagle - no schematic. Release uncertain since the FRAK/3 has already gotten more development and is 99% compatible (it adds a minor hardware incompatibility for a configuration that was never supported).
PAK68/2: There's a printed schematic in the c't magazine, additionally I've scanned an existing board. Partially exists as an eagle layout, but currently on hold. This project can be resumed and completed with the existing documentation I have. A release is planned for the future.
Panther/2: I have the original PCB production files, as well as a set of boards. A conversion to eagle is planned but low priorised. This project hasn't been started yet since I just recently gathered the documentation files and there's still a small amount of boards for sale. Aim of the project is, aside from digitally archiving the boards, to reverse the schematic.
PuPla/2: The layout is ~90% finished. This project currently has the lowest priority since there are still 20 boards available for sale. Aim of the project is, aside from digitally archiving the board, to reverse the schematic.
Other sideprojects:
The eagle layouts for the PLCC-DIL 68k solder- and SOJ-DIP300 TAGRAM plug-adapters which are byproducts of the project are released "as is" for private use at this point. The CPU-adapter is an untested prototype, the TAGRAM-adapter is an early concept and needs additional work (but should be able to produce usable gerbers). These will be updated along with the other projects in uncertain intervals.
http://www.file-upload.net/download-835 ... r.zip.html
Unsupported, but possible future projects:
Generation 3:
PAK68/3-030: Outdated revision with no advantages, lacking some minor features. Nothing planned.
PAK68/3-020: Outdated revision with partial advantages (020 instead of 030), lacking some minor features. Layout and schematic can be easily adapted from the 030/030A design. Nothing planned.
FRAK/1: Outdated revision with partial advantages (SIMM instead of EDO/FPM sticks, lower overall capacity). Nothing planned.
Panther/1: Outdated revision no advantages. Like a Panther/2 without networking functionality. Nothing planned.

Generation 2:
PuPla or PAK-Puffer: Outdated revision with minor advantages (DIP/through hole parts only, lacks features). This board has been replaced by the PuPla/2. Nothing planned.
PuSTE: Outdated and prone to causing problems. The PLCC-DIL CPU solder-adapter I layouted combined with a PuPla/2 completely replaces this. Nothing planned.
PUK: Functionality is already included with the PAK68/3, but is missing on the PAK68/2. A possible future project.

Generation 1:
PAK-68: A schematic was printed in the c't magazine. A possible future project.
PAK-68 SRAM Daughterboard: A schematic was printed in the c't magazine, but no copy is available to me (Issue 1, Year 1988). A possible future project

Changes FRAK/2 -> FRAK/3
- all FRAK/2 specific patches/fixes mentioned in the manual are already represented in the layout/schematic.
- the layout was changed to a 4-layer design (better ground connection, more potential for overclocking).
- an additional adress line!
- the through connectors for the adress lines from the PAK68/3 and the sockets for their driver chips were placed as far apart as possible so the optional terminator resistors can be soldered easier than before, now it _should_ even be possible to solder them after everything else has been built (0805 SMD, 3 DIP rasters of space).
- all jumpers on the PAK68/3 got through connectors on the FRAK/3, so you don't have to take apart the 2 boards to change an option. Options which are set by the presence of the FRAK are hardwired, options which are permanently set by the hardware of the PAK68/3 have been excluded. Additionally the generated clock frequency gets forwarded to the PAK68/3 in a neater way.
- PAK68/3-020 specific components were removed, since the FRAK never had GALs for this combination.
- some more minor changes I can't remember for now.

Wanna help? This paragraph will be updated soon-ish. For now either contact me via PM or at "mos6502@peacock.com - with the animal being replaced with 'gmail'"
Basically anything along man/woman-power, physical objects (chips, sockets, etc.) or funding can be used. Use your creativity for now.

Major crysis! All layer data for the PAK68/3 has been lost :( Only the unrouted signals remained with no backup available - that's a good 100 hours of work lost.

Just kidding of course, I just finished "porting" the published schematics to Eagle and above are all parts aligned like their are on the finished board.
Incredible someone untied this knot back in 1993 when PCB tools weren't as powerful as they are today.
Now all that's left to do is update the scheme to the A-revision and link it to my layout - then it's time for a "second pair of eyes"-check followed by prototypes.

Layout and schematic have been linked together, except for 1 small mishap (in the published scheme - which wouldn't affect a standalone PAK68/3 at all) and 2-3 minor inaccuracies (the symbol for pullup resistors was a little confusing and pins connected to VCC via their own line rather than thermals weren't reflected) everything worked nicely out of the box. This tunes me very positive my layout contains no errors.

Expect prototypes to be made soon-ish :D

Major step forward: An user from the Forum of the Verein zum Erhalt klassischer Computer (Club for the preservation of classic computers) just donated a considerable amount of money.
Also: The PAK68/3-030A schematics can be considered as finished (just need a "second pairs of eyes"-check).

Re: Project rePAK

Post by Shockwav3 »

Good news.

The FRAK/3 has entered pre-prototyping. The layout is considered done and pakman (Holger) is currently developing the GAL chips. Total capacity of the FRAK/3 has been upgraded to 256MB TT-RAM.
The PAK68/3-030 will also get a newer revision, to go with the FRAK/3 (users with earlier cards will have to cut 2 lines and solder 2 wires on their PAK to get the full 256MB goodness). Never the less, the PAK68/3-030B remains compatible with the previous cards.

Additionally: Panther/2 & PuPla layouts have been finished. Just like the schemes for the Panther/2 slot-card and the PuPla/2. Once the Panther/2 bus-adapter has it's schematic drawn and some minor cleanups completed - those files might be released. Since those boards are rather simple compared to the PAK68/3 and the changes very minor (only included the patches mentioned in the manual) I'm considering to skip physical prototypes. I'll update you on that soon.

Can I haz hardware?

Just to update the projects thread under development:

FRAK is a TT memory expansion and PAK68/30 is an accelerator, right?

Can both work together?
They have DIL connector so I pressume they can work in any Atari ST/f/fm and Mega (plusAmiga 500/2000), but do they fit in an Atari ST case or in the Mega`s?
STe and Mega STe have PLCC68000. Can there be a PLCCversion or work with an adapter? Would them fit in a Mega STe then?

Thanks

Hey, don't feel bad - visit my thread here where I was learning about the PAK and installing it into
a STacy. Anyone standing next to me will immediately feel taller/stronger/smarter/better looking,
etc,... :lol:

Try this URL and run it through google translate for lots of good info on this subject:
