Re: 8050 ROM dump

Yeah, sounds odd.

Jim, I'm not sure what you're asking since all the images are on Zimmer's, 
but FWIW I have two 8050s (one with the 901887-01/901888-01 set and the 
other with the 901482-03/901482-04 set) if I can help in any way.

This doesn't seem right. Surely commodore used EPROMs while developing the 
drives, before they made masked roms. Perhaps it's a matter of selecting the 
correct speed EPROM? Afaik the two CPUs don't access the same rom anyway. 
I'm sure I've seen drives with EPROMs direct from commodore.
