I’m still not 100% sure if this is a 3300 or a 3400. It’s in a BA400X chassis, and after looking at the manuals last night, it seems like it’s closer to the 3400. My familarity with Q-Bus MicroVAXen is limited to MicroVAX/VAXstation II’s, and a MicroVAX 3.
After getting a power cable (the only one at PCH Cables was a 3’ one, and I didn’t want to wait for more to come in), it powered right up, but is failing 4 tests.
I quickly learned last night that “TEST 9E” prints all the tests out to screen. This effort is making me wish I had a DEC LA50 plugged into the terminal. :-)
It starts counting down diagnostics at “41”.

I think this is indicating issues with the DSSI interface. The system has two RF73 DSSI drives, which sound like they spin up. It also has a TK70 tape drive. It says it has 4MB and 16MB RAM, all good.
One odd thing is that the KA640-A seems to plug into another board, before the DSSI drives. I’m getting ready to dig into that, and find out what that board is.
