I just posted a new scan from the RCS/RI library: a third party (Stone & Webster) assembler for the IBM 650.

So... the first person to post about my new edition of the photo book for our computer museum is an ex-employee of Cray Research. Killer.

The second edition of my computer museum photo book is out! It's a bit pricey, but the print quality is MUUUUCH better than the old version. (And it's 50% longer.)

Working on new photos for the second edition of the photo book I did for our computer museum. (Primarily doing a 2nd ed to get higher quality printing. Previous copies quality is just not good enough.)

There is no airflow whatsoever inside the ROLM militarized version of the DG Nova, so the IC's and other components straddle metal bars that conduct heat to the edge of the board, and from there to outside the chassis.

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.

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.
