[vcf-midatlantic] Need Yamaha C1 EPROM images

[Ethan]

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.

Link of floppy files and my (prob bad) bios dumps:
