Re: Modified ST hassles

These two boards- The IDEAL_IDE interface & The Magnum 8Mb need to be combined! (They both already support TOS2.06 control) Your (almost) talking about the H&N Multiboard, aren't you? That one used two 30pin. SIMM Sockets. But added an 16Bit ISA Slot. Got one of those together with an HBS64...

Atari Testkit All-In-One

Hello, Currently I'm using a standard EPROM card with four sockets for 27C256 each, but I'm fed up with erasing/programming new EPROMs each time ant pull them out of the socket, push them in again and so on... So I'm going to design a PCB for the ROM-Port on Atari ST/STE/TT/F030 which can hold a sin...

Re: "Interesting" TT Motherboard layout issue

I got the same Rev. of TT. Different Fast-RAM Cards fit perfectly (Atari 4MB/aixTT/MagnumTT). The Daughterboard ist NOT soldered, but plugs into a PGA socket beneath. Theres a brown/black pair of cables leading to the 32MHz quartz - correct? IIRC you can remove the daughter-board and put a 68030 CPU...

Re: First PAK board attempt...

What puzzles me a bit is the ad on pg.1 that announces a PAK with 68030 AND TOS2.06. I still have my PAK/3 somewhere and we always used TOS3.06 because it was said that 2.06 does not initialise the 030's PMMU. Theres an easier way to boot into 3.06 on a PAK/3 than using a TOS Card with 2.06 on the m...

Re: Unknown Network card

There is an auction on ebay.de at the moment with the same AMD chip IIRC - but different card with 4 EPROMs on board for MST slot. Will try to find it this evening. A buddy of mine gave me that card 10+ years ago. Never used it (lack of drivers). I'll try to make it work with Mint - but I'm a total ...

Re: TT Rev.J needs repair

Ahh.. okay. Understood.

Had a look at three TT mainboards yesterday. One is probably scrap - still has its MCU. I'm thinking of un-soldering this one and see it the other TT can be repaired with it.

Unknown Network card

Found an unknown network card for the MegaST in the cellar these days. Never had drivers for.

Anybody knows the manufacturer, has drivers or manual?

Re: TT Rev.J needs repair

each riser pcb has a socket to allow it too be flashed
by some sort of central mcu like a atmel or pic controlled board... from rs232 from pc or usb etc...

right now you're talking Chinese to me :o
What do you mean with riser PCB? I know what an 16bit ISA Riser card is, but now I'm puzzled.

It would be better if someone with the actual magazine (C't issue 9, 1993, page 170: "Allesfresser -IDE adapter für Atari ST") could scan those pages in high resolution, and hopefully someone with the bare PCB could scan that as well and turn it into a PCB layout image file). If there is ...

Re: TT Rev.J needs repair

Well, sounds logical to me. That means that the waitstates are "measured" on boot time?

I'm asking on a German forum if someone needs items from Best... I'll definitely order a MCU.

Re: TT Rev.J needs repair

well, probably.
Is there a way to use a socket for the MCU or are they always soldered to the mainboard?

I put in the EPROMs from my good TT: no change at all. Still MCU bit 7 never set and it does not recognize TT-FastRAM.

Hi simbo, believe it or not: that's exactly what I'm trying the last hours: want to burn a new set of TOS3 EPROMs. The TOS3.06 EPROMs in question are TI 27C010-15. I always used an old 1040 with 3MB (enough space for a RAM-Disk) with Maxon's Junior-Prommer and Mega-Module (for 1MBit+ EPROMs) to burn...

Hi Simbo, Bit 7 of the DIP switch just enables HD-Floppy formatting from Desktop, right? I switched it on: HD-Floppy formatting enabled via Desktop, off: only DD formatting enabled.

Re: TT Rev.J needs repair

I removed the 2MB STRAM board and the TT-RAM = minimal RAM is now 2MB STRAM. I did a RAM-Test with diagnostic cartridge 1.4: no errors. The MCU bit 7 error still occurs when I press 't'. I think that the error message leads into a wrong direction. If MCU means STRAM MCU and a data line is corrupted ...

@simbo thanx for your long answer - really didn't expect that! The TT board in question is a Rev.J with soldered 68030 (onboard).
