I picked up two HP cards that I think are from a HP 3000 but I can't find
anything about them online. They're large cards with the number HP
93788-80041 on them and they have a daughterboard on them that's marked
93788 CII Chipset. Does anyone know what these are?
Joe
Jules,
Did you see this?

That sounds like a pedistal system. They also made a table top and rack
mount systems but the manual mostly talks about the pedistal systems.

The manual says that there's also a XMD controller for LARGE (ESDI?)
hard drives that only controls HDs. It uses an 8031 microcontroller and has
a large connector (34 pin?) in the top center of the card and two smaller
ones (20 pin?) on each side of it. And also a XMT card that can be used to
control up to two Pertec 1/2" tape drives. That card also uses an 8031 and
it has two large connectors on the top edge. I'm pretty sure that all three
of the cards are XYLogics cards. The interesting thing about them is that
they use I/O Parameter Blocks to communicate with them just like the Intel
MDSs do. I'm not that familar with the structure of Intel's IOPBs but this
manual has a detailed description of ones that these cards use so someone
could check them against the Intel description and see if they're the same.
If you'll post a picture of your card I'll compare it against the drawings
in the manual and see if it matches.

I'd be interested in a kit for my 11/05. Think the overlay is shown in
the Printset so I should be able to do my own ovelay when I find the
manuals.
Thought the KM-11 was also used on the LA180, been too many years to
guarantee that (it could have been the RX01, one or the other).

I'd really like to exchange some Off-List mail with a Listmember who is
fluent in Apple Mac Comms - I've got a very obsucre set of intelocking problems
that is keeping my G4 from talking over it's ethernet port, which I need it
desperately to do - so I can download some patches for *another* program that
is misbehaving... aarrgh...
If anyone is familiar with the intricacies of the TCP/IP implementation
(currently running OS9.2.2) and could offer some advice, I'd be very
grateful...
Please respond off-list - thanks!
Cheers

Hello, all:
I'm trying to make disk images of a CP/M disk from an MS-DOS machine
so I can send the images to some one else to generate disks. The CP/M
machine is a Micromint SB180. The PC is a standard Compaq 386. Both machines
have HD 5.25" drives although the format of the disk is standard 40-track.
I've used Copy-II-PC to make disk-to-disk copies with some success
but the CP2PC software can't make images. I have not hooked-up the CP2PC
floppy controller board yet, but that could be another test option.
I've also used Teledisk 2.12, which can make disk images but I
haven't been able to successfully regenerate a test disk image into a
working diskette.
Are there any other disk imaging programs out there for the PC that
can read and archive CP/M-format disks?
Thanks.

Both are HD?? Are you using the first 40 tracks on the CP/M side
as compared to alternate 40 tracks on the PC side? Usually when
a PC program thinks it is using 40 tracks on a HD drive, it skips
every other track. Unless the firmware on the CP/M machine has
modified low level code for seeking tracks, it will single
step between tracks. This could be an issue when doing images.
You can always do some direct to controller stuff. Several
of the books on writing code for PC's describe how to setup
the DMA channels and talk to the controller. I've used that
to get around the problem of the first track being single density
while the rest of the disk was double density.

The fundamental problem with RMS is that he cannot make a distinction
between free software / open source *philosophy* (which ought to be
applicable to *all* platforms regardless of technology) and his GNU
project, which is one very specific technology with one very specific
set of *technical* design decisions behind it (which I happen to disagree
with most emphatically). The problem can be seen in how www.fsf.org
redirects to www.gnu.org (or at least it did last time I visited).
