A few years ago, I borrowed this Teletype from the museum to do a photo shoot in my studio. The box in the base is a Bell 101, the very first commercially available modem.
Kobaïa and Salome were, of course, very excited. They love the old telco stuff.

Quick Reference poster for MIT's TX-2.
Most of a KDF11, the second generation microprocessor version of the PDP-11. (The MMU and optional FPU are separate chips.)
Early Cisco (CSC/3) and SGI (IP2) multibus 68020 CPU boards.
The beginning of the end of the minicomputer era.
We made some progress on the Cray at the museum today.
We suspected the reason the Cray I/O subsystem was unresponsive was dead NVRAM chips. We wound up configuring a new NVRAM chip with all the correct values in a separate machine of similar vintage (Sparcstation 1+) and then moving the chip over to the Themis VME board in the Cray.
It worked! We can now talk to the Cray I/O system.
Getting closer to booting the machine for real...
Working on the Cray (J90) a little bit today. Trying (and failing) to talk to the IO subsystem from the management workstation (Sun SS5). Pretty sure we know what the problem is.
