Great info, U106 and RAM keeps appearing as culprits in other people’s posts.
Last couple of questions if I may.
If it’s ROM, is h8000’s ROM compatible with Orville? Would Eventide have one for sale?
Is there a chance to obtain Orville’s service manual?
The reason I’m asking is because I’m based in UK and the service center I contacted (Source Distribution) no longer services Orville. This may be the case with others too. Also, I assume the LED’s on the mainboard are giving certain messages that could help troubleshooting.
