Re: Devpac 3 - Where to start?

There's a series of articles in ST Format (issues 21 to around issue 28 iirc) on how to write ST games in 68000 machine code with Devpac. That's probably a good place to start (its where I did).

Re: STBook/STylus test board found

I just found this board in the basement. Am I correct: it looks like a test board for an ST Book? Fascinating! There's 128k of ROM and 64K of RAM on the board but also a three-wire serial EEPROM… There's also two GAL/PALs (one for I/O, one for Memory?) on there as well… Any chance you could dump th...

Re: Help Compiling TOS 2.06/2.08/3.06 in any language

I already looked into that, but stopped when i found out that apparently some of the sources of 4.04 where compiled by Lattice C rather than Alcyon. And i have no idea which version they used. There are also quite a lot compiler-switches which have an influence on the generated code, so it might be...

Re: Modded Atari 1040 STF, seeking help identifying mods

The middle switch makes the monitor image go funky, so overscan could be it, although my monitor doesn't seem to support that mode. It will -- overscan needs a software patch applied to make it work... Why would it need a RTC (and so many wires attached)? The ST (by default) doesn't have a clock so...

Re: Modded Atari 1040 STF, seeking help identifying mods

I'd hazard a guess that the battery is connected to a real-time clock chip (the 8573P is a Philips clock chip) on the board with the 40-pin socket (I imagine the socket was used original to prototype it externally). The wires around the TOS ROMs are probably for some form of TOS switcher (although t...

Re: 1040STe+ (STe w/ 286 CPU) PCB layout

From what I've seen, apart from the 286 and the IDE interface, this would have been a regular STe without any additional video hardware. Also, I think DOS games weren't the primary target, but rather productivity / business software -- much like with the AT Speed add on cards. Not just like the AT-...

Re: Another Falcon in need of resuscitation..Please help! :-)

The other thing to watch out for is if the Falcon doesn't have an expansion card fitted (which yours sounds like it doesn't) then it needs a jumper fitted over two of the pins on the expansion connector (I can't remember which off hand). I'd have expected the power light to have come on -- although ...

Interesting. I've never seen it advertised but that means nothing at all.
