Someone asked a question about it privately, I researched today and found the answers so I'll post here as well for posterity.
The HP 2610A printer that I have.... 2610A was the HP designation for the Control Data Corporation 9322 Printer. HP sold the printer basically unmodified (as far as I can tell) and slapped their label on it. Mine seems to be in rather good condition so I suspect it will be restorable. In addition, I unearthed a full set of manuals/docs for the thing. Most manuals I have are HP ones, but a few in the binder are CDC manuals for it. At the same time, I also found several binders of docs for the HP 2754 (also have one of those). 2754 is the HP designation for the Teletype model 35KSR. HP sold the printing terminal/reader/punch with minor modifications and slapped their label on it. I have a complete set of docs, mostly HP branded but some (wiring lists, lubrication, disassembly, etc.) are Teletype branded.
