These folks hosted the UNIX 50th Celebration and had a physical PDP-7 that
was used to bring up UNIX V0 (after first getting it running on SIMH). That
later was not easy because the original PDP-7s (like the one Ken had access
to) did not have disk storage. BTL had paid DEC's Custom Special Systems
(CSS) to splice a Burrough's disk that DEC was selling using for the 15 and
later the PDP-9.   It started with splicing reverse engineering that code
to build a simulation of that disk into the simh, so we could ensure that
UNIX ran—finally, modeling that HW with a custom microprocessor-based board
with an SD card with a functional replica of a PDP-7 I/O interface on one
side obeying the device registers and operations that UNIX expected to see.

The LCM-L folks were incredibly gracious and generous. I am so sad to see
their collection go away. In particular, I hope the PDP-7s and the CDC-6500
find new homes.

Clem
