HP-1000 12044A 12825A HDLC Interface manuals available anywhere?

[Glen Slick]

I don't see these manuals online at either bitsavers.org or hpmuseum.net.

Does anyone have copies of them available?

12044-90001 HDLC Direct Connect Interface Hardware Reference Manual
(12044A for A/L-Series)

12825-90001 HDLC Direct Connect Interface Hardware Reference Manual
(12825A for M/E/F-Series)


I have more than one HP-1000 CPU. Just curious what it would take to
connect some of them together running 91750A DS/1000-IV software.
