From time to time I get asked about the Teletype ASR33
Parts List (much
harder to find than the other 2 volumes of the maintenance manual)
and
the service documentation for the Facit 4070 paper tape punch (which was
used by just about all computer manuafacturers in the early 1970s...)
I was poking around on www.hpmuseum.net and _both_ are on that site. The
trick is that :
HP2752A == ASR33
and
HP2895A == Facit 4070 with HP modifications (an extra interface PCB, etc)
In the fromer case the 3 volumes of the Teletype docs are available to
download separately (the HP manual just gives the modifications to make
it HP-compatible, and the schematics), tin the latter case there is one
manual, most of which is the Facit service docs and parts lists.
