For anyone that cares, here is a list of the configurations of my HP
9825s. Notice there's some funny stuff here. Some are marked 9825A on the
back but 9825B in the front next to the display. Several are marked 9825T
under the paper cover. #4 says A on the back, B next to the display and T
under the cover! You figure that one out!
Many of them have a list, under the paper cover, of ROMs that are
installed internally in the machine. The ROMs listed are not the same on
every machine and they're listed in differnt orders. Also some machines
have different amounts of memory.
The box mentioned on some of them is a small box that extends out the
back where the power cord plug in is located. It looks like a noise filter
was added on to some of the machine.
Some of these also have the operating system located in a plug ROM
located in the side of the machine.

Has large warning label on outside top warning the user not to install any
ROMs other than the 98211 matrix ROM or the 98217A Flexible Disk Drive ROM.
Installing any plug-in ROM that is already built into the calculator may
cause damage the machine.

I remember seeing a picture of this machine-- it was a link-belt of
cards in a loop, with holes punched through them. They would pass by
this 'reader' thingie which would 'read' the card with a matrix of
metal rods poking through the holes.
Using cards in such a manner would be like kinda using a ROM chip as
a character generator for a CRT display. Hence the wisecrack about
CGA is actually not far from the mark! ;^)

The nice thing about mechanisms is that all one needs to understand
them theoretically is a finger, some Advil, and the ability to
multiply/divide. Following a circuit board is much less intuitive.

Well, I'd give computer credit to Babage's machine, ca. 1896, IIRC. He is,
after all the one who coined the phrase "computer."

Unless they were working for the company of the same name that made PC Mice.

Right. The manual states that 640x400x2 is a "tweaked" CGA mode.

I just tried to run it on my desktop. First question it askes was "What
22xx series of GRiDPad are you installing to?" Back to the drawing board. I
doubt it'll work with the old 1912. If I could find GEOS, I'd install it.
Only version I have is for the C-64.

Don't tell my z80 that... I debugged the interface using Basic right down
to sector reads and writes.
I read the spec as it must support 1mbyte/sec minimum to the host
not that it required 1mbyte/sec from the host. The IDE is locally
buffered just like SCSI so there is no need for speed save for the host
can make requests very fast (Pentiums). IDE is also an async bus.

A USRT is far mor than minimalist as the NS* con troller is really just

Or doing it insitu using a old drive as a positioner.
