I totally agree!
I think this is why I find the peripehrals to be as interesting as the
CPU in a lot of caes. Ubnderstnading the cotnrol state machine of the
HP9866 printer was as interestign to me as understandignthe microcode
(and sequencer) of the HP9830 that drives it.
I totally agree with that, too. I remember when I was doing my thesis, I
printed it on the department's Qume daisywheel printer. They had the
service manual with complete schematics. It was very interesting, with
analogue servos for the carriage motor. A very nice piece of equipment.
Not to mention the 11/40 we used, or the big 80 MB Ampex disk drives.
