I suspected that was the case. I’m currently only on a serial console, until I solve my monitor cable problems.

Once I get a monitor attached, I plan to run it through the full screen diagnostics.

DS12887+ from Amazon.

I should have a monitor cable by Thursday, assuming I don’t find the one that I’m sure I have before that. Since I’ve been searching for the cable for several months, I decided to buy one off eBay, and I have the parts I should need to hook it up to a modern monitor. Wow! FedEx just delivered the cable, so I guess I’ll be hooking it up shortly. It looks brand new.
When I dug back to the mice, I found I have two VSXXX-AA hockey puck mice, so I’m even more convinced that I have a monitor cable somewhere. I also found a AUI loopback with the mice.
The next part I need is a C15 power cable for MicroVAX 3300, I’ll see about picking that up tomorrow or Wednesday. I don’t believe that I’ve ever tested the MicroVAX 3300. A friend gave it to me when he was moving out of his apartment. Given that it’s only 2.4 VUPS, I can’t see me doing anything with it at this point. I should also test my MicroVAX III while I’m at this.
