It's an early stage of the project but I have put all the hardware design and software on GitHub so anyone can follow along with the project. So far, with the driver in RAM, I have successfully got both reads and writes to a 32 MB virtual hard drive image stored on the Raspberry Pi. Next steps are preparing the driver for EPROM. There is a lot of work needed to improve the code including error handling and tests.. It's very much a proof of concept at this point but appears to be successful so far.

Hi, I did a project in 1995 similar to the card you did, so I can share (apologies if not the correct thread) :) www.clintech.net/romcard/
