I borrowed a couple of CF IDE adapters from a friend. IMG20230713122051~2.jpg No luck with running an optical drive using these, either. Same issue. I can even run that dual card adapter with a 512MB & a 1GB card, in master/slave without a problem. This must be some weird issue with the Ide …

1GB industrial card arrived, and unfortunately it behaves like the other >512MB cards I've tried. I.e. fine until I turn on the optical drive, then freezes after memory count. I'm out of ideas, short of trying other CF IDE adapters, but at this point I don't want to throw any more money at this. IMG …

I've done this exact thing. Ordered one of those boards and added PS2 for mouse. Worked easily. Just added the headers and bridged the required points, didn't need any other components, though I expect if you want IR too, they'll be needed.

Ah, I hadn't considered the CF card had something to do with M/S logic. My 512MB card is an industrial type, while my 1GB card is a Transcend CF 133.

I quite like the K6-2+ CPU for flexibility, you can push it from 200 to 600 MHz and enable/disable L1 & L2 caches all from software (Setmul) without touching the bios. I have Setmul configure the CPU just right before running whatever game. It'll even play Quake 3, if you pair it with a voodoo 3, …

As difficult as the task may be, I have started to map the traces from the pictures you provided, at least those that don't end somewhere under a chip. @majestyk Would you be able to take a few more pictures, some sightly angled maybe, to make the shadowed areas clearer? And do you have a multimeter …

Wow, ok, didn't expect someone to actually have one. Thanks for sharing. So, at least it is clear that there is nothing proprietary about the chips used, some ram & buffers, so that's good news I suppose. One day maybe my ebay saved search will ping something, not that it has for some years now 🤣

I am actually using a pico atx-at adapter, that's where the -5v is being generated. My issue is, the main board is some industrial type, and doesn't have a normal power connector, and it's missing any input for -5v, so I need to get it to the ISA some other way. I am no electrical engineer but I'm …
