  2. Or just get an Eiffel interface and use a PS/2 mouse and keyboard.
  3. Older came with DD, newer with HD. Same with TT. However the Mega STe came pre pepared for HD if you only got DD. It's just a GAL chip and a HD drive I think. EDIT: WD1772 needs changing to AJAX.

  5. This is pretty good as well: Part 1, Part 2.
  6. You won't get double speed with 16Mhz. It's like 25%. Bitter doesn't do that much different. I would say a HDD. UltraSatan or a IDE interface internally . ParCp-USB or NetUSBee for transfer. Can you solder?
  7. Have you hold your finger on all the chips? Any of them getting extremely hot? Warm is okey, you should be able to hold your finger on them. If it is burning it is a sign that is is shorting. MMU or perhaps memory chips hot? Otherwise you need to start checking if you got clock signal on all chips and if you got signal on address lines and data lines. If anything seems strange or a missing signal. Or checking cold solder joint or cracks. Anything suspicious really. When does it start bombing by the way? At boot screen? Directly after power on? Does it have time to start accessing the floppy drive? When booting with diag cart in you could connect to another computer via a null modem cable and see if anything appears on the other computer with a communication program on it. 9600 baud 8N1 (8 bit char, No parity, 1 stop bit). RAM seems to look as they do on factory Mega 1. I got 256 in my Mega 1 as well.
  8. Nope. Falcon has SCSI in the back though. But no STe has it from factory. Maybe someone hacked one in? Do you have YT link? I'm really curious now.
  9. Nope. Normal STe didn't have SCSI. But it have ACSI. But you can't connect a SCSI HDD directly to that. You need a adapter for it.
  10. I read this at https://forum.atari-home.de/ written by Dal on facebook: Later:
  11. The decoupling capacitors would provide a more stable feed and eliminate spikes. But it isn't necessary. Tried changing the 74LS244 and 74LS373? Otherwise try put your finger and feel if any chip is hotter then the others.
  12. Yes, you already made a topic about this some time ago:
