If you can convert the disk image to a .imd disk image file, you can try it in UniPCemu. UniPCemu tries to emulate the physical disk layout (including seeking etc.), maybe that's going wrong somehow? It might be reading the entire track incorrectly (wrong sector orders etc.)? Since it uses a read …

If we use the command mask 1F, 71 & 1F = 11. 11 is not a valid command that I am aware of. Programming the FDC involves writing several bytes in succession for the operands of different commands. If an earlier command was valid but not implemented and its operands ignored, then its possible that …

I got my hands on a neat Random Technology KC-216 PC. I played with it a bit, and it has some issues, but in general it worked ok-ish. It uses a unique external PSU, with a DIN-5 plug that provides +12v, -12v and +5v. This morning I tried turning the PSU on but it did not work anymore. I opened it …

Hello, I think you need more of an XT-CF-Lite v.2 or something like that for the 5150. I actually have one installed. I was able to install dos from the real floppy drive. But a gotek would be nice too, in case i was not able to find real floppy media. I saw videos of people using it in a 5150, so …

I'm trying to boot my IBM 5150 from a Gotek emulator, running the latest FlashFloppy firmware (3.39). The gotek drive appears to be detected on boot (no errors), and there is a short seek, but then the PC goes to basic instead of booting. The oled display shows that the drive quickly seeks up to …

I got an ISA TV Card, and I'm unable to find any documentation for it. It seems like a passive card, meaning that it gets only power from the ISA slot. It has VGA pass-through connectors, which works. I guess that it is operated by some kind of IR remote that will switch it from "Computer Mode" to " …
