Somebody should grab these... The 9816 is a small 68000 machine built
into the same case as the monitor. It's about the same age as the Mac
128 I think, but IMHO a much nicer machine. There's no internal mass
stroage device, but you have an HPIB port (which will connect to HP disk
drives like those 9121s (although a double-sided drive is very
useful...) and a serial port. You also have 2 DIO expansion slots.
There's normally either 128K or 256K of RAM on the CPU board. It's not
hard to upgrade it to 1M though (involves replacing 32 RAM chips, adding
a TTL chip and a rrsistor and cutting some links). I can give you details
if you want to do it.
One currious construcitonal feature is that you can remvoe all the PCBs
apart from the PSU by undoing 2 quarter-turn fasteners and just one screw.

If nobody grabs these, I'll drop Dallas another line, since he's here
in town and I'll stash them away against the day that someone
expresses an interest.
I'm not all that interested in vintage HP computer gear (at least not
68K bases stuff), but I don't mind storing it for someone.

I've been discussing the machines with Dallas. I'm very interested in
these machines!

I know the feeling :-). Shipping to England isn't cheap either -- just
abpout always the cost of shipping exceeds the price I paid for the item
on E-bay. Oh well...

It sounds like there are people interested so these machines will be
saved. Good! If someone here gets them, feel free to ask me how to
upgrade the RAM (f they don't have 1Mbyte on the CPU board), etc.
I;ve enver seen a 9816 with internal drives. It's the same case as the
HP120, HP150 (but without the enlarged top cover for a printer), etc.
It's pretty tightly packed in there, there's no room for drives.
But one common system configuration for any of these machines consists of
a turntable on the desktop, then an HP9121 or 9122 dual 3.5" floppy drive
unit, and then on top of that a tilt unit containing the computer (which
contains the CRT). That may look like an all-in-one machine with CRT and
drives in one unit.
I can't believe you made the other somehat common mistake of assuming the
thing with a CRT in it is just a monitor and all the logic is in the disk
drive.

For some reason, I thought these came with 2 3.5" internal floppies.

That wasn't me. I know better--I think I've seen one of these before-
-an incredibly crammed-full 68K CPU board.

Yes, the 9816 CPU board is pretty well packed. So is the 9817 ('shoebox'
style case) board. Theyr'e the same size, but the latter contains no user
RAM, instead thaere's an MMU (and not a single-chip thing). There are
other changes to the keybaord/sound circuitry too.
I've never tried it, but it appears you could put hteh 9816 CPU board in
the shoebox cae or the 9817 board in the 9816 'monitor style' case with
just some link changes.
Incidnetally, the disk drive unit does contain a microprocesosr (6809)
and it is possible to download and run programs on it (there's a
diangonstic command for this purpose). Something else that I have never
tried.

I have sent a message also as I am very familiar with these units and
go to Eugene every other week.
