PDP-11 boards come in two flavors Unibus and
Q-bus the are either 2 high,
four high, or six high. Generally only Unibus and PDP-8/a boards are 6
high. (I don't think they ever made a Q22/CD/EF backplane.)
They did make one -- DDV11-B hex wide 9 slot. However, the E/F section
isn't bussed, only having +5/+12V/0V connections (ABCD are normal Q-Bus).
It's meant for third-party development, and there are no hex Q-bus boards. >> Coming soon to www.computergarage.org - the
