At Rice in the early 90s the department was "Electrical and Computer
Engineering" if my hazy memory serves.
The genealogy of Computer Science departments (and their curricula) (at least
in the US) is also weird and historically-contingent. Basically it seems to

Another consideration with the TC02 is the small buffer. I don't know
what tape speed your drive runs at, but we lost a lot of sales to Dilog

Hi Guy,
If you didn't see this, it may be of interest:
http://everist.org/NobLog/20131112_HP_1000_minicomputer_teardown.htm
It won't help you identify your system model, but could be of help with
disassembly.
Funny coincidence that we have the same name, and similar HP-1000 minicomputers.
OK, thanks.
Is there a sheet somewhere that I can use to decode all of these part numbers?

Don't know the date of the unit shown, but in the early-mid 1970s, we

2113 implies a 21MX-E; the nine-slot version is a 2109 while the fourteen-slot
