Josh,
If this doesn't work out contact me, I do have some spare boards for the HP
9830A.
Thanks! I appreciate the help.
You can use the key caps form a HP 264X to replace
lost key caps, if you
need switches I have some cherry switches which can replace the original
with some modification (longer leeds).
That's good to know, thanks. Any idea on the model of the cherry switches?
The infotek boards are very rare, so be careful with
them, if you ever want
to get rid of them let me know ;)
That's the gist I've gotten from the research I've done. I may hold
onto them for now :). I think I was misled by the labeling of the
photos I found on the HP Museum site yesterday. The HP Museum provides
this manual for the FP-30/MX-30:
http://www.hpmuseum.net/document.php?hwfile=5741
And the following for the MP-30:
http://www.hpmuseum.net/document.php?hwfile=5368
Based on the FP-30 docs, it's pretty clear that that's what I have in my
machine (it occupies slots 4 and 5, with the RX-30 ROMs filling slot 6),
while the MP-30 is an upgraded controller for the 9880 drives (it looks
like it replaced the PCB in the interface that plugged into the rear of
the machine). And perhaps the MP30 labeling on the EPROMs on the FP-30
boards indicates that it has added support for the MP-30 expansion.
This is not entirely clear from the documentation...
I also have the RC-30 "ROM Clock" which is a real-time clock that fits
into one of the internal ROM slots.
What I don't have is the special MX-30 memory board(s). Normal 9830
memory is incompatible with the FP-30, so without it I'm not going to
get anywhere. And I'm guessing these are nigh unobtainable.
This would be a pretty sweet machine, if I could just get it running...
