  1. The chips creep out of the sockets after all these years. As DarkLord said, remove chips, use contact cleaner in socket. Reseat chip. So probably just bad connection. Cold solder joints or hairline cracks on the board could be hard to find if it comes to that point.
  2. It's the Mega ST blitter patch. It usually fitted on a small board soldered directly to the 68k chip.
  3. https://docs.sidecartridge.com/troubleshooting/#floppy-emulation
  4. I made a comment about that in the thread when he made the space bar clips. It looks like you should be able to cut/file the the end of the space bar ones to make the return key clips. Nothing I have tried though.
  5. You can download the files from https://www.thingiverse.com/thing:3887995. There is shops/sites that prints your 3D files for you. I have ordered from jlcpcb.com before and they look great. I'm sure there is some shops in UK that will do that as well.
  6. Do you have a 35y old PSU in the STe? Kinda sounds like some capacitors is not up to specs anymore.
  7. Exxos have them. But I'm sure Best Electronics probably have them as well.
  8. The ribbon cable need to be attached up side down on gotek drive.
  9. Yet another board revision. Interesting they added buffer chips on the ram. I wonder where in the timeline this was created. Would have been nice to see inside the shifter box (probably no change there) and under the disk drive.
  10. If you use it as a disk emulator it doesn't load the game. You mount the whole *.st (or *.msa) as a floppy which take some time (pretty fast). Then the disk is accessed on A:\. So then it will load as a normal disk. All disks doesn't work though. It depends how the game/program is accessing the floppydrive. So it is used sort of like a gotek.
  11. That explains a lot. SCSI wasn't a standard back then.
  12. I have tested v1 and v2 of BlueSCSI. It worked fine. But I can't remember anything specific I did. And I don't have access to the stuff at the moment so I can't check the INI file.
  13. If I remember correctly, someone did do a fix and merged it on github with agranlunds github. I think he fixed the PCB. I can't find that thread at the moment. I also did a PCB fix which is located here and on other forums. I never did github so it is sort of "hidden". It fixes the bodge wire need and confusion with CAS1L and CAS1H.
  14. From the link I gave. Download binary. Unpack, run "install.prg". Ener your name. Leave all the rest blank. It ignores it anyway. It should install itself in "C:\EDGE". When run you should see under "Diamond Edge" menu and then click "about Diamond Edge" that it is registered to you with regnr: "E-0000-25".
  15. There are "fixed" agranlund pcb. That is why there are different instruction
  16. Probably the auto boot driver/boot record that is wiped. Try installing it again (on the Atari). Which HD driver are you using?
  17. https://www.atari-forum.com/viewtopic.php?f=15&t=43308
  18. In the PSU? Probably a Noctua NF-A6x25. Be sure not to run the fan in "quiet" (less airflow) mode with the cables that is included in the package. The PSU needs full airflow from the fan to cool it sufficient.
  19. I have used ACSI-SCSI adapter board by Inventronik and tried with both BlueSCSI v1 and v2 on a Mega ST. An Atari ST(f,m) is the same so should work fine. But other/any(?) ACSI-SCSI adapters should work. Like Link2 and the other ICD boards (Advantage, Advantage Plus, AdSCSI). There is reverse engineered of those boards but I don't think anyone is making/selling them.
  20. Isn't each chip 1-bit? So filling the whole pcb would be 2mb. Since is seems that it is a solderless upgrade you can only upgrade bank 1 and bank 0 is filled with 0,5mb on the mother board. Otherwise if you got a 1040 you need to disable bank 1 first. Could be that the first version of MMU couldn't handle 2,5mb. But ram chip fault is a very common problem as well.
  21. Is it this? https://docs.dev-docs.org/htm/search.php?find=z-ram Or did different z-ram exist?
  22. Probably a serial (rs-232) mouse for PC. So you can use it on Atari with a driver and connected to the serial port. But with an adapter since Atari serial port is 25 pin. And since it will need a driver, it will have somewhat limited use.
