HP9816

[Tony Duell]

I've just bought a partially defective HP9816 (aka HP9000 model 216) on 
E-bay. Let me emphasise from the start that the seller declared the 
problems in the E-bay listing, so I am certainly not complaining.

Anyway. one problem is that the power-on diagnostics mention an 'Alpha 
Video' failure, and then give a memory address/data failure message. I 
think the address is in the text video RAM area (it would be on a 9826 or 
9836), so I suspect one of the 2K SRAM chips on the text PCB (the larger 
one standing up next to the CRT). I will do some more tests.

Another problem is that I am missing a keycap, I think it's the left hand 
shift key. I have the small, compact keyboard.

So a couple of questions.

1) Does anyone have a 'junker' keyboard that I could buy a keycap from. 
Or any ideas as to making one

2) Does anyone have the service manual (or is there a scanner version on 
the web, Google found nothing, and I couldn't find it on the usual sites 
[1]). Yes,. I know it'll be a boardswapper guide, but I might was well 
read it if it's available.

[1]. What's up with http://www.hpmuseum.net? I get all sorts of 'SQL 
errors' when I look at the doucmentation index, and most of the manuals 
are no longer available :-(
