Re: Suska board

I've just had a reply from Wolfgang saying that the chosen FPGA cannot run _slower_ than 16MHz*. While I don't understand how this mean the cores could've been tested in-situ during development, it definitely means that very few demos (and some games) will run correctly. It's possible the VHDL could...

Re: NEW MSTE/TT & ST PSU ? (well not really)

I must confess, since the ST already has an external power brick I think a picoPSU is the best choice there. I desoldered the exising power connector, put a picoPSU internally and it supplies the 5/12/-12 in ample amounts to also be used for other internal mods like an HxC slim etc ... Of course, th...

Re: Suska board

He keeps asking me to extract the files on Troed's Closure demo. I keep telling him he won't let me do this It's not about letting ... there are no files :P It's true old school track loading. There exists no filed debug version either, I use all memory from $200 and up so bye bye TOS after the boo...

Re: LED's and using the right colour for the right Atari ST Model

Yeah these are missing from the table. 1040STF with red led, might have long button drives but not always, and I think all of them are 8.01MHz CPUs (since they don't need PAL color clock)

Recapping floppy drives

(a.k.a, bring back the dead) I have two piles of floppy drives in the closet. One of drives that no longer work, one of working drives. Usually I try really hard to source Epson 340 drives so that I can move the front bezel and eject button from the dead 380 to them, but after a while I run out of d...

Re: When is a ST not a ST anymore ?

it was only the 260ST and 520ST{F}{M} didn't have the blitter, the 1040ST{F}{M} did have one, it's still an STFM, just with the option installed. Umm no. Some STF(M) motherboard revisions do have solder pads for a blitter, but no socket, and the same motherboards were used for both 520 and 1040 jus...

Re: C103175 REV 1 (520 STFM)

This looks a lot like my C103414-001 board. It has the same IMP chipset, layout is similar only on your board the memory is through hole. On my board, the memory is also SMT. The pinout of those DRAM’s should be the same as on mine, only the package is different. On my board, we’ve removed the 256k...

Re: When is a ST not a ST anymore ?

BUT. if we ran at exactly 200% speed "across the system" then demo coders can likely tweak software and use the same tricks again.. So while a booster will break stuff, timings are exactly 200%. So software can be fixed, and we still have the option to run compatible software on a accelerated machi...
