The RICM just picked up a PDP-11/40 chassis that was modified to accept a
PDP-11/23 board set. It also contains a custom board to interface the
PDP-11/23 to the original PDP-11/40 front panel. It is quite an
accomplishment to get the Q-Bus board set working in the Unibus chassis.

Oh now that's fun. And useful. A blinkenlights Qbus machine! If it's
not impractical the mods should be documented so that others may go
reproduce this setup. How fancy is the custom board?!

What boards exactly? Are you sure it's not an M7133 11/24 board instead?

Very interesting -- is this a homebrew affair, or does it use something
like an Able QNIVERTER to do the job?

I'm guessing the Qniverter.
