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...

TIL how the old #Cray #supercomputer worked. Apparently it would run the same sequence of instructions over many different data sets at the same time. It could do lots of math in a hurry, but only if it was lots of the same math.
It could also run ordinary one-thing-at-a-time software like Unix, but then it wasn't any faster than an ordinary one-thing-at-a-time CPU like the Motorola 68000.
This all sounds awfully familiar. Isn't that how GPUs work?
