Re: Manuals needed... (HP12063A)

For the control store it’s the 12205-60002 Frontplane. The 12205A Control Store is pretty uncommon; the frontplane equally so (probably more so as folks seem to just throw those away and keep the boards when scrapping systems).
For the memory any of 12222-60002/3/4 Frontplane would do fine. Those do appear on eBay, but at prices well outside the budget of a hobbyist. I’ve been thinking about fab’ing one for myself and whether that’s a realistic proposition. The DIN connectors (well, close enough for a bit of careful filing to get a decent fit) are common enough and small-PCB fab is inexpensive, even in 4-layer. However I’d settle for a 12222-60001, which would at least let me attach one of my four 12220A 768k cards.

The Frontplanes are also listed in the 5955-8896 A-Series_CE_Handbook.pdf Chapter 8, Replacement parts, Page 8-4.
The PN is 12222-6000x, x= # of memory cards.
What did you need ?

Thanks you Roland. Now if I could just find the pair of frontplanes that I need to get my A900 card-set “activated” (memory and control store). Stephen Hanselman had indicated earlier this year that he had both, but he’s never responded to my messages :-<. Can anyone else help me?
Unfortunately I don’t own the „HP 12063A Isolated Digital I/O Interface“ Manual.
But you could find some bits in:
- 12060-90003 L-Series Automation Interfaces User Information R0184.pdf Section V (5)
- 24612-90011 HP1000 A-Series Computer Interface Diagnostics Reference Manual Feb_92.PDF, Chapter 12 contains hints about wiring of the Test Hood (page 12-5). Check archive.
I hope it helps.
Thank you Dave.
All 3 manuals are now in the HP Computer Museum website (www.hpmuseum.net) as well..
You can place them on the file section of this group.
