Eine Beschreibung und Bauanleitung von  
Markus Elsken@OL2  
 
 
 
 
 
So, hier nun die Anleitung: wie fädel ich mir ein 16MB-PS/2-SIMM in den Falcon? Eigentlich ist  
es ja ganz einfach, man braucht nur:  
 
- eine Lochrasterplatine min. 120*55mm  
- je eine Buchsenleiste zweireihig 50polig und 30polig (oder auch 2x17pol)  
- ein PS/2-SIMM-Sockel, gerade  
- Fädeldraht (am besten im Fädelstift)  
- ca. 30cm Telefondraht o.ä.  
- einige Stütz- und Abblockkondensatoren - und natürlich ein 16MByte PS/2-SIMM, Fast-Page (kein EDO!), ohne Parity  
(schadet aber auch nicht), 60ns, single-sided.  
 
 
 
 
Mein konkretes Exemplar sieht so aus (von oben gesehen: Lötseite):  
 
 
                                    Datenleitungen           1/10"

Das PS/2-SIMM steckt mit den Chips nach unten im Sockel, weil sich das SIMM nur "von hinten" einlegen läßt.  
Der Rest ist reine Fleißarbeit, es müssen sämtliche Adress- und Datenleitungen (A0-A10, D0-D31) sowie  
alle RAS- und CAS-Leitungen via Fädeldraht verbunden werden. 5V und Masse werden via dickerem Telefondraht angeklemmt.  
 
 
 
 
Die Belegung des PS/2-SIMMs:  
 
 
 1 - Gnd     13 - A1      25 - D22      37 - MP1     49 - D8      61 - D13 
 2 - D0      14 - A2      26 - D7       38 - MP3     50 - D24     62 - D30 
 3 - D16     15 - A3      27 - D23      39 - Gnd     51 - D9      63 - D14 
 4 - D1      16 - A4      28 - A7       40 - /CAS0   52 - D25     64 - D31 
 5 - D17     17 - A5      29 - nc       41 - /CAS2   53 - D10     65 - D15 
 6 - D2      18 - A6      30 - Vcc      42 - /CAS3   54 - D26     66 - nc 
 7 - D18     19 - A10     31 - A8       43 - /CAS1   55 - D11     67 - PD1 
 8 - D3      20 - D4      32 - A9       44 - /RAS0   56 - D27     68 - PD2 
 9 - D19     21 - D20     33 - /RAS3    45 - /RAS1   57 - D12     69 - PD3 
10 - Vcc     22 - D5      34 - /RAS2    46 - nc      58 - D28     70 - PD4 
11 - nc      23 - D21     35 - MP2      47 - /WE     59 - Vcc     71 - nc 
12 - A0      24 - D6      36 - MP0      48 - nc      60 - D29     72 - Gnd 
 
 
MP0..MP3: nur bei Modul mit Parity  
 
PD1-4 sind uninteressant, MP0-3 müssen (sofern vorhanden) mittels eines Pullup- Widerstand  
(unkritisch, ca. 1 - 10 kOhm) auf 5V gelegt werden.  
 
 
 
 
Die Belegung des 50poligen Falcon-RAM-Ports:  
 
 
[Pinanschluß an PS/2-Modul: * = 1/39/72, ** = 10/30/59] 
 
 1 - Gnd [*]    11 - D9  [51]   21 - D1  [4]    31 - D19 [9]    41 - Gnd [*] 
 2 - Vcc [**]   12 - D8  [49]   22 - D0  [2]    32 - D20 [21]   42 - Vcc [**] 
 3 - D15 [65]   13 - D7  [26]   23 - M0  [Gnd]  33 - D21 [23]   43 - D27 [56] 
 4 - D14 [63]   14 - D6  [24]   24 - Gnd [*]    34 - Gnd [*]    44 - D28 [58] 
 5 - D13 [61]   15 - D5  [22]   25 - Vcc [**]   35 - Vcc [**]   45 - D29 [60] 
 6 - D12 [57]   16 - Gnd [*]    26 - Gnd [*]    36 - D22 [25]   46 - D30 [62] 
 7 - D11 [55]   17 - Vcc [**]   27 - Vcc [**]   37 - D23 [27]   47 - D31 [64] 
 8 - D10 [53]   18 - D4  [20]   28 - D16 [3]    38 - D24 [50]   48 - M1  [--] 
 9 - Gnd [*]    19 - D3  [8]    29 - D17 [5]    39 - D25 [52]   49 - Gnd [*] 
10 - Vcc [**]   20 - D2  [6]    30 - D18 [7]    40 - D26 [54]   50 - Vcc [**] 
 
 
 
 
Die 30polige Leiste:  
 
 
 1 - Gnd [*]     7 - A5 [17]   13 - Gnd [*]    19 - A10   [19]  25 - CAS0L [40] 
 2 - Gnd [*]     8 - A4 [16]   14 - Vcc [**]   20 - A9    [32]  26 - CAS1H [42] 
 3 - Vcc [**]    9 - A3 [15]   15 - Vcc [**]   21 - WE    [47]  27 - CAS1L [41] 
 4 - A8  [31]   10 - A2 [14]   16 - Gnd [*]    22 - RAS0  [44]  28 - Gnd   [*] 
 5 - A7  [28]   11 - A1 [13]   17 - Gnd [*]    23 - RAS1  [34]  29 - Vcc   [**] 
 6 - A6  [18]   12 - A0 [12]   18 - Vcc [**]   24 - CAS0H [43]  30 - Vcc   [**] 
 
 
Die Zuordnung von D0-31, A0-10 und WE dürfte klar sein, für RAS/CAS gilt folgendes:  
 
 
 
Falcon          PS/2-SIMM 
------------------------- 
 RAS0  (22)     RAS0 [44] 
 RAS1  (23)     RAS2 [34] !!! 
 CAS0L (25)     CAS0 [40] 
 CAS0H (24)     CAS1 [43] 
 CAS1L (27)     CAS2 [41] 
 CAS1H (26)     CAS3 [42] 
 
 
 
 
 
Am PS/2-SIMM sollten alls sechs Anschlüsse für die Versorgungsspannung angeschlossen sein,  
außerdem schaden einige Kondensatoren (100 nF) direkt am SIMM-Sockel nicht.  
 
 
Zu den MemSize-Pins M0 (Pin 23) und M1 (Pin 48) an der 50poligen Leiste, sie müssen wie folgt  
angeschlossen sein:  
 
 
          1MB ST-RAM    4MB ST-RAM    14(16)MB ST-RAM 
M0 (23)     Gnd            offen          Gnd 
M1 (48)     Gnd            Gnd            offen 
 
 
 
 
 
"Offen" bedeutet High-Pegel, da Pullup-Widerstände auf dem Mainboard für definierte Pegel an den  
Pins 11 und 13 vom 74LS244 IC (U42) sorgt. Sinnvoll ist eine Bestückung mit Jumpern, wenn verschiedene  
SIMM-Größen ausgetestet werden sollen.  
 
 
 
 
 
 
Noch etwas zur Praxis:  
 
 
Da das Pinout des SIMM-Sockels leider nicht in Standard-Lochraster paßt habe ich einen geraden Sockel flach  
auf die Platine geklebt. Mit Kunststoffkleber (UHU plast o.ä.) klappt das vorzüglich. Daran läßt sich dann auch 
 wunderbar fädeln...  
 
 
Probleme  
 
 
Ein Fehler, der möglicherweise auch bei anderen Falcons auftritt: Die Karte funktionierte erstmal nicht, obwohl korrekt  
gelötet und überprüft. Ein halbes Jahr früher hatte ich das gleiche Problem mit einer Falcon Wings und 4*4 MB SIMMs.  
Kein Bild und mit dem Testmodul erschienen nur ein bunter Bildschirm. Mit vier 256k-SIMMs lief sie (MemSize-Pins  
entsprechend gejumpert) auch die selbstgefädelte Karte lief mit einem 4MB-PS/-SIMM einwandfrei. Als Ursache hatte  
sich dann endlich eine Unterbrechung (kalte Lötstelle?) an der RAM-Stiftleiste des Falcon-Boards herausgestellt - A10  
kam nicht oder nur verstümmelt auf der Speicherkarte an. Nachgelötet: läuft :-)))  
 
 
 
 
Warnung  
 
 
Standard-Disclaimer:  
Das Falcon-Board ist in der Rev. A/B ein 6-Lagen- und in der Rev C/D ein 4-Lagen-Multilayer. Bitte sehr vorsichtig löten,  
Schäden sind i.d.R. nur sehr schwer zu beheben!

I built my own 14mb card last week using an old crap ATIN memory card with the sockets removed, and a new 72pin socket from an old PC mobo. Its great what you can do with solder and hotglue :wink:
Can't believe it worked first time. Still get some sparklies at 25mhz, but no artifacts at 20mhz. This is with a CT60 fitted with solders.

Anyway. I am considering getting a small batch of Rodolphes CTR14 cards made for as little as possible cost, so I need to know how many people want them???

Hi guys!
Count me in, if it's a standard upgrade not requiring a CT board.
(of course, price is relevant :D )

Hi guys,

Post by PBS07 »

in other thread in this forum we already mentioned, that I'm preparing little batch of my own RAM cards. More info at http://www.volny.cz/boban07/RAM_kartice/
This week I want to order parts, so if you are interrested, please let me know. Just for sure: all of my cards are with SIMM fitted and tested with 25MHz BUS ! My RAM card replaces "original" RAM.
With regards,
P.B.S.

I decided not to follow up making of the cards for 2 reasons: I only had about 5 pre-orders, and then I found someone else was taking orders for the same, so I am ordering mine from them...

I believe you have to use a 16MB SIMM module but the Falcon is only able to address 14MB of it

Yeah, buy a fastram card, or get yourself a CT60/63.

Know anywhere that has schematics for a FastRAM card or is it a lot more complicate dthan the standard RAM board?

I think thats a bit unfair. When making devices such as these in such small quantities the price per unit will inevitably be high unless you have free access to the equipment needed and can get small quantities of components at a reasonable price. A lot of component suppliers have pretty large minimum orders by our standards and this makes it very difficult to get all the parts cheaply.

Indeed!

Most places don't want to know you unless you are buying in 1000 piece increments!

The price of the CT63 is eminently reasonable! As already mentioned, the cost for components rises almost exponentially when bought in "retail" quantities as opposed to buying them on a per-truckload basis. Compared to all the disposable, buggy cards for the peecee that can be made by the gazillion for a penny a pop, Czuba tech has very high overhead costs. The CT60/63 is a high quality board that has gone through a process completely unheard of in the PC world. Its called beta testing. And it, too, costs money.

In the PC world, "beta testing" is done on the cheap, usually like this: First by fast-tracking into immediate production some random, unfinished engineering project, giving it a mysterious pop-culture bullshit "code name", renaming the file "design_goals.doc" to "product_specifications.doc", announcing it with great fanfare to "the media", releasing to the public whatever piece of poo rolls off the production line with the goal of selling as many units as possible in the shortest amount of time. These unwitting saps are your beta test group. Great concept for companies unencumbered by a sense of morality. Anyway, the point is you're buying a board that works as advertised, has been fully vetted and will stand the test of time, not some haphazzard throwaway for the PC.

One other factor to consider is resale value. If you drop 300 Euros on a CT-63, you haven't really "lost" anything! That card is as good as money in the bank. If you doubt it, look at the prices Cyberstorm accelerators for Amigas go for on ebay. A few years ago I actually got MORE for a MKIII than what I had paid for it brand new five years earlier. Stock Atari Falcons get $600+, even 15 years after they were made. PCs go unclaimed in the trash after about 6 months. I've never even seen a Falcon with a CT-60 in it on ebay, but if there was I have no doubt it would sell for a minimum $1,000.

If you have a problem with the price, look at the CT-63 as an "investment". :)

This week I want to order parts, so if you are interrested, please let me know. Just for sure: all of my cards are with SIMM fitted and tested with 25MHz BUS ! My RAM card replaces "original" RAM.
With regards,
I recommend this card to anyone. It's cheap and works perfectly at 25Mhz!

No. The CT6x is extremely cheap. I highly doubt he gets any profit from it, at least not much. If you had any idea of the costs involved when making smaller batches of high-tech stuff like this, you would agree.

I could make some 14 MB boards (without simms) if we can get some buyers to hold the price low. I think 20-30 Euro is possible or even less.
