The device is what's controller sees on the cable. Converter is a bridge between the device interface and the device implementation, it is a device from the IDE controller's point of view, and must behave as a device. I've checked with ATA1, the only time when the device can drive that line on the …

Is the oddness on the end of 8237 left over stuff from a sticker ? I cannot see any thing like burned cap or trace. Does the relay have a funny smell ? What does the back of the board look like ? Just curious. The back of the board is fine, but the 8237 is strange. The discoloration didn't come off …

Over the years, I've collected some Logitech Bus Mouse cards and a "Microsoft InPort Device Adapter" card. I only have serial and PS/2 mice. Is there any use for these cards if I don't have the older style bus mice? https://deskthority.net/wiki/InPort#:~:text=Microsoft%20InPort%20is%20a%20deprecated …

This was the first motherboard that I started working with when I dug my box of 1990 computer stuff out of storage. Had good CPU coverage, WB support, ps/2 mouse, 3.3v power for the ISA slots through the supplemental power plug. I was lucky enough to have a power supply with the right connector on …

I powered it off and didn't see any damage. I looked over the capacitors with a magnifier and didn't see any burn marks or holes. Now …

I do wonder if anyone will ever make a "retro" display once other technologies have caught up to CRTs. At this point in time, nothing can really replicate a CRT's motion clarity or resolution + refresh rate flexibility, so purists will still have reasons to use them for retro gaming. If we ever get …

The top is buggy (ROM chip select not properly done). The bottom looks like the DIL (dual in line) version of the top. The middle one uses a GAL, a programmable chip, but I wonder if it has enough I/Os to do the decoding of the IO address and the ROM address? Sounds like you are saying that all …

I am not surprised that your SD->SD adapter-> Cf bridge->Cf to ide stack had issues. The CF->IDE adapter that you show does not look like it has a voltage regulator on it. It can only provide 5V power. My experience has been that Type 1 SD->CF bridges require a CF->IDE adapter that can provide 3.3V. …

Early ATi cards had very mediocre DOS performance, both in VGA and VESA modes. Probably, it was never their priority, due to rise of accelerated GUI environments. At least they're faster than budget Cirrus Logic crap or some obscure chips outside of big OEM market, but that's it. Are you talking …
