These things are extremely rare in general, at least
out in the wild.
This is only the third to surface, and of all three now documented on the
web (or at least known to be) they are all completely different.
Actually, I have a fourth one (IIRC, I got it from a list member) that I
haven't put on Applefritter yet. It's like Sellam's Systematics in
design concept, but is shoddier and has a back like the tempest SE/30.
Curiously, like the SE/30, this tempest Mac is also missing it's
motherboard and back panel. Does anybody know if motherboard removal was
a common practice in decomissioning tempest computers?
Has anybody actually ever seen or gotten to experiment with equipment
intended for emanation monitoring?
