So, a few questions:
- Is there a specific ROM version I need in order for the KA650 to
recognize the VCB02? I have V1.2/0123 which seems pretty early (given
that I've seen references to 5.3 on the 'net). If so, anyone know
where I can find a dump?
- What keyboards is the VCB02 compatible with? I'm using it with an
LK201 from my VT220 currently, and all four LEDs are lit constantly,
which starts me to wondering...
- Are there any restrictions on slots/card ordering I should be
concerned with? This is in a BA23 backplane (which originally housed
a MicroVAX I)
Thanks!

I think I've answered my own question for the first one -- I found the
V5.3 ROMs at http://www.dunnington.u-net.com/public/DECROMs and burned
them, successfully upgrading my KA650 to 5.3. (I made copies of my V1.2
ROMs just in case)
The machine now definitely sees the VCB02 (it shows up under the SHOW
QBUS command) and appears to be trying to use it as a console at
startup, but is failing:

Performing normal system tests.

Normal operation not possible.
Based on my investigations, the ?62 test code is the console QDSS test,
which would point to a failure of the VCB02 in some way. Anyone know
how to decipher the test results?
Thanks!
