Well, the hardware docuemtnation of the machines themselves is not to my
liking, but the docs I've seen on the DIO cards is good. And the
programming manuals are certainly clear and seem to be complete.
HP used to produce excellent documentation, that much is certain.

How much memory? My 9817 has 2 megabytes.

I'm likely to be doing a lot of interfacing and not that much processing
if you see what I mean. I susepct 512K would be enough for that. I can
certainly give it a go.

I am going to have to see if a 9133 can low-level format a drive -- the
actual machanism is a standard unit (ST225 or something like that). I am
told it can, and I do have the command set somewhere, so it might be
Of course the drive unit in the 9154 is very much HP custom, with a
_strange_ interface (parallel 8 bit data bus for head
positioning/control, and then the raw data lines for read/write). So no
real chance of using something else there.
How useful is a hard drive? I know the previous owner of my 9817 ran it
from a 9122 floppy drive only.
