We have one complete with the vinyl case.  i have to check with my partner to see if we can let it go.  Down side it's in Carson City Nevada so shipping would be quite high.

That's OK. I wouldn't try to ship a monitor internationally anyway. Very high
chance of it being broken. Like this: http://everist.org/NobLog/20200208_neglected_561.htm#st

The missing monitor is quite possibly lost somewhere in the ACMS storage spaces. It might yet
turn up.

Ah. I misread that "any", you mean "any groups"? This one seems to cover most of the non 80-series one. I was not even aware that there was a 80-specific group, until a few days ago.

I have the pdf of the disc manual insert(2.3MB), it’s a reasonable copy.  I also have the 7912 service manual and it’s an excellent copy(18MB).  I know I should have hard copy spares of the 79xx CD handbook and maybe the CS80 programming manual.  We’ve been throwing out pallets of books and I just don’t know.  

I’ll upload the .pdf’s and check the hard copies. Yours for shipping if I have them.

After study of 11202A TTL I/O manual I've found the easy way how to communicate modern computer with any 98XX which is working with this cable.

The answer is Arudino....it has enough digital pins to feed all flags and data pins required to send ASCII data back and forward  - you can simply join necessary pins of 11202A board with own programmed pins of Arudiono unit.
(additional electric circuit is not need). So far I've tested sending messages from 9821A to PC........fully succesful :)


HPDisk piggyback board

Anders
 

Got the prototype PCBs today. This is for those who are using my HPDisk (http://www.dalton.ax/hpdisk/) with computers. The board plugs into the AUX connector and has an RTC, a display and three switches (up/down/enter). The switches lets you select what image to use as drive 0, drive 1..3 are fixed and determined in HPDISK.CFG.


It works like this: https://www.youtube.com/watch?v=ytZfeUKNaAo



The idea is to mount the extra board at right angle to the main PCB in a box like this:

Are your HP9830 keyboard missing a few keytops? Maybe you can find it in
the picture I append. I offer very small number of key tops and key
switches to those who restore a HP9830 and are missing a couple of keys.
Might work for HP 264x keyboards as well.

Since they have seen quite some sun the key tops are not in perfect
shape. But a slightly dull keytop is better than nothing. Right?

They are free for the cost of shipping (from Sweden).
Are these the same as those used on the 9825B? They look very
similar. I'm in need of two switch mechanism, a "6/&" key top (top row,
not numeric keypad), and a "Continue" key top for a 9825B. I think the
9830 doesn't have the "Continue" key?

Dave,

I don't think they are the same any 9825A full stroke keyboards I have seen have a cross on the top of the post, in any case I can probably help you out with key switches and even the keytops.  BTW if you want to make that 9825A into a 9825T I have extra card sets.

Looks like a nice desoldering job there on those switches :->!


It was took a while to get the switches lose. They were sort of  press-fit into the frame. Some kind of notch that made them stick. Some of them were really hard.
