it's powering up, but just a few LEDs are on and no sound or response from the keys to the voiceboards.
The Z80 is fine, too.
Thanks,
Thomas

Subject: [vintagesynthrepair] OBXa diagnostic EPROM needed
Hi guys,
thanks for approving my membership to this list :-)
I'm restoring an Oberheim OBXa 8-voice and looking for the diagnostic EPROM with paperworks for it. A BIN would be fine.
It's REV C mainboards and has a Numera Midi interface installed.
Will probably remove the Numera first to get the machine up and running and see if it's the Numera that's causing trouble.
Fortunately all the voiceboards are fine.
Any help would be great and appreciated :-)
Best regards,
Thomas
