Hardware / Atari 520 STFM - Issue 4x Mult...

Last post by DigitalSkunk - 13-04-2025, 21:59:14

Hey guys, I am probably overlooking something silly, but I am a bit stuck.

• I got Petari's awesome TOS Improved 2 versions, and Atari's original TOS 1.04, 2.06
• On 2x 27c4001 EEPROMs
• A17 and A18 (Pin 30, 31) are TOS toggles. This seems to be working. Switch off has both pins at 5v. I used 33ohm resistors I had laying around, is this high enough for protection?
• With both switches grounded, A17 and A18 low, it successfully boots TOS 1.04 original.

I can't get the other three versions to boot, and am not sure what to check next.

I have a strange revision of 520 STFM, ROMs are under the PSU, 2 chip version. So, to be less cramped and reduce the chance of ROMs, GAL shorting to the bottom of the PSU shield, I actually installed the GAL on top of the 68k, and ran a fairly long CE1 line from GAL 15 pin to Pin 22 of new ROMs.

• Pin 24 on new ROMs are pulled up from the socket, connected to GND on mono. (OE)
• Under pin 24, I ran A16 to Pin 2 of new ROMs.
• GAL pin 15 CE1 is running to Pin 22 of new ROMs. This pin is inserted in the socket still.
• When I unsoldered the CE blob jumper on the board, TOS 1.04 original quit working until I soldered it back on 1M pad.
• A16 and A17 pads are still soldered on 1M like stock.

I hope this is enough info to start. Thanks in advance for nay help anyone can offer. I am rather confused at this point. lol

Yep. you'r right. Ax=ctualy I saw pages about this game, but I'm not horror fun - well, even if it is not claimed as horror game.  Anyway, I will do this one more month too - graphic is not bad, well, not for me anti-horror one :-)  . So, expect it in next month.

 As may see plenty of French educative games (few with Engl, De, Ita, Esp lang. too) done - they are usually with nice graphic .

 Many games needed diverse fixes, finding floppy images with all good files ..
Most interesting was case of double error in code for screen delete . Loop counter for deleting 32 KB was given without prefix for immediate data, so what was used is content of some low RAM loc, and value was 2x bigger than needed, so even with correct prefix it would damage RAM area above screen buffer.
 It crashes even with running from floppy if there is 4 MB RAM in Atari - not so rare case of such error in games. It seems they they did not have test machines with so much RAM around 1989 .

 I plan to add couple games more, and then will write here about how to get it ..

I had a TT once. Really nice machines but I ended
up selling it.

I could kick myself - really wish I'd kept it now.

And another case with some bad ST image dumps online:  Herewith the Clues !
There are ST image files at atarimania and at emu-land.net . In both cases there are 4 corrupted files (1 on first, 3 on second floppy) . Luckily STX images at atarimania are OK, so I was able to convert them to good ST images - there is no copy protection.
Did hard disk adapt. Soon will put it on site, and good ST images too .

Did some educational games too  - by Micro-C - yep, French . Need yet to do couple, test and add usual screen, box shots converted for ST(E) . Hardest part was pretty unusual copy prot.

Indeed interesting discussion. But I never had some CT60 and like accelerator. So, can not say anything about driver requirements for it.  What I made was fast RAM support for TT . It was long time ago, with TT what I got for some months for SW development, test.
 As remember ACSI driver for TT needs to perform disk transfers only with ST RAM, and that's because DMA chip is same as in Atari STs (I even tested speed, and it is same too, despite TT has much faster RAM) . So, if SW asks some transfers with Fast RAM it needs to use some little ST RAM there will data loaded from disk (or saved to disk from), and it needs to be loaded with current content for next section transfer before DMA transfer to disk, or needs to be saved after loading from disk to Fast RAM. Something similar is needed when loading/saving to/from odd RAM address .
 It was tested by me and users, and I did not receive any complains from TT users.
