Re: OB-Xa Diagnostic EPROM needed

2012-11-28 by Doug

Yes, my best guess is that it is a bad EPROM. Unfortunately I don't have 
the image files for the MIDI version. I have image files for the
original so I tried to remove the MIDI board and put in the original
EPROMs. There was no flickering but no sound either. I'm not sure
if i need to change anything else to revert it to original non-MIDI.

So a set of image files for the MIDI version would be useful too.
