Well, I'm sure there's a DEC diagnostic for the DLV11-J, but I have no idea
what it is.

I did have a little ~20-instruction program that tests the receive and
transmit interrupts, I'll send you the URLs for the source, and ODT script,
forms. (Not sure what forms of object formats you can load into the machine.)

Luckily that didn't fry anything. (I'm not looking down in disdain, I've made
a few similar mistakes myself! I usually try and stop and check twice every
time I go to turn the power on after I've fiddled with the hardware, for
precisely that reason.)

I wonder if that's because there's no drive? Is this test suppose to need
one, I forget (I think you said but I'm too lazy to look :-).
