I've been working on documenting the hardware in the early Altos x86 machines and it would be nice to find a copy of the eproms from a 586. I tried asking Dave Dunfield about this, but never got a reply. Has anyone heard anything from him lately? I know Eric Smith was trying to contact him a few months ago about extending the known disk types in Imagedisk (specifically adding M2FM as one of the formats) but I don't think he ever heard anything back.
