[sdiy] Anyone worked on an E-mu Ultraproteus?

[Thomas Hudson]

First off, thanks for all the drone suggestions, I’m having fun looking at all the possibilities.

This may be off topic, but I have an E-mu Ultraproteus that powers up, but the screen is blank. I replaced the internal lithium battery but that didn’t help. Just wondering if anyone here has dealt with one. Someone suggested it might be a problem with the power supply.

Thanks
