Wow. I can’t thank you enough. That fixed it. I’m surprised that site didn’t come up in any of my searches. This is one piece of gear I’ll never let go of. They don’t go up for sale very often, and when they do the prices are outrageous.

Again, thank you,

Thomas

It looks like there's supposed to be a diagnostics mode (look at the bottom of that page). Can you boot into diagnostic mode and initialize the memory?

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
