[ARC5] Tape

[Clare Owens]

I still have one hanging on my pegboard in an honored place - and I still
use it!  And I was an SE not a CE...  But I used to do some hardware things
for control system and teleprocessing computer interfaces with the real
world and always stayed buddies with the CEs...

I also have one old (large for 1620 computer) and one new 30ga wire wrap
tool, a delete tool, the two sizes of screw starters and a couple of spring
hooks.  And a bunch of other IBM trinkets, like the plastic Hex adders,
Hexapawn games, History of Mathematics charts, etc., etc.

Ah the good old days.
