We’re releasing a stalled or abandoned prototype every few days while Seeed Studio is on break. We put a lot of work into these projects, but they’re still missing major components and testing. If an abandoned project sparks your interest, we may have PCBs to get you started.
The XT-IDE project is a Vintage Computer forum driven project to develop and manufacturer an 8-bit ISA IDE controller. It allows any PC/XT class machine to use modern IDE hard drives or Compact Flash devices for long term storage. (From the XTIDE project wiki)
Our version of the XTIDE controller replaces the 7400-series logic chips with a CPLD, a chip that can be programmed to replace dozens of individual logic chips. The logic is designed in software by drawing a schematic, and then uploaded to the CPLD. New logic circuits can be designed and tested without making new hardware each time.

Schematic and PCB are on the XT IDE disk controller wiki.
Hi! Do you have any plans on building and selling XT-IDE boards? I would be interested in acquiring one for a PC-XT compatible which had its MFM/RLL HD controller dead. I had read about the XT-IDE project before, but I can´t find a company that builds and sell them (I know a little bit of electronics but got too little time for soldering it all myself). Thanks!
Unfortunately there isn’t a high demand for these, so we probably won’t make a batch. I believe someone has kits of the original XTIDE board, and they will solder it for you for a few dollars.
