[sdiy] Oberheim OB-X repair help

[Maarten Halmans]

Hello,

I am repairing a Oberheim OB-X, it is an early 4-voice and there is problem 
with 2 of the Eproms. I found the data for the newer version online but I 
really need the early version because some hardware changes where made. Does 
anybody have the bin or hex files for them or knows where to get them, so I 
can burn some new ones.?
I am also looking for the second edition of the service manual, I can only 
find the first edition online.  Maybe I can get the newer software to work 
when I do some hardware changes. I already tried the newer software, a lot 
of stuff is working properly but the LED's on the fronpanel are not selected 
and updated.


Thanks in advance,

Maarten
