Aye, laddy, 'twas a PDP 1 with sense switches on the front that one did
indeed toggle in the paper tape boot program (to get it to where it
could read from other media), a green oscilloscope-style CRT for a
monitor (complete with crosshatches IIRC), a real teletype console, and
the ability to run simple fortran programs that did beam optic
computations and displayed a simple visualization of same.  The PDP
itself was quite large, and I was told that it "had a few bad bits..."
but that they usually didn't affect the outcome of a computation.

I was kidding about the teeth, though.

Next (if things go as they usually do) we all have to kid around about
IBM 5100's and QIC (floppies are just plain too modern for me:-) but if
I do that the Titorheads will attack and I'll have to once again
unconvincingly deny that I am, in fact, John Titor.
