>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.
