Longshot but looking for the bios and 3rd chip EPROM images from the Yamaha C1 286-10 "music" laptop. I posted the floppy disk dumps that are pack in including some developer dox (including pinout of expansion connector!) in both disk image and zip format online. I also posted the EPROM dumps that I have -- I noticed text from the Copyright notices is corrupted so I'm thinking my issue with the computer is the eproms are going bad. There sems to be a lot of flaky/dead units out there (when I can find them.) I think the machine is strange enough not to be able to use other generic bios copies.
