There was a brief discussion here a little over a year ago regarding
manuals for the M2351A Eagles. What I didn't see was if the manuals were
ever scanned and made available/on-line. Tony or anyone know? I have two
M2351As and would like to return them to operational status.
Thanks,
John
some new updates on the catalog page: www.rdrop.com/~jimw
Item 124 might get someones attention...
Then there will be a slight break in the updates for a week or two while I
get caught up with shipping, moving, and other localized annoyances...
Thanks;

Hello,
I am rebuilding a Northgate ZX-Portable (almost done) but need some
information on the AC charger.
The AC Adapter output connector (the part that plugs into the computer)
was hacked off when I acquired the computer. I've bought a replacement
connector, but still need information on the AC Adapter pin-outs.
Does anyone have a similar machine, and could tell me the pin-outs for
the battery charger, or offer some advice on where to find this
information. The part number for the Northgate AC Adapter is 850-0215.
I am new to this list, and glad to have found it. Classics are great!
Thanks in advance,
Dan Lee
Hello,
I am new to the list.
My classic computer collection is mainly DEC but I
must use "classic" HPs at work. Hence my current
problem.
We have multiple HP9000/300 computers connected via SRM
to a HP9826 computer running SRM ver 3.12. We also
have several standalone Viper board based PCs.
My current problem is that one of the hard drives
attached to the HP9826 has died. It was a HP7937 HP-IB
drive. I believe it was a CS80 device. I have backups
made with a HP9144 tape drive.
We could buy a refurbished drive. We were quoted $1300
for a HP7937. I would like to avoid that. Since I only
need a few files from the backup and my application
could run from the Viper board, if I could get the
files into a MS-DOS format, my problem would be solved.
I looked through the archives and ran across a thread
"HP storage formats on ss80 protocol disks". It seems
work has begun on a Windows program to read at least
LIF volumes attached to a NI-GPIB board. I have acess
to such.
The files are RMB ver 5.13 files. The drive that died
was not the boot device.
Couple of questions:
1) What format is the SRM backups in? LIF? HFS? Other?
2) Peter Brown, would you share your software?
I am also open to other suggestions. If you have a
HP7937 drive or similar, we can talk. Either purchase
or trade. We have a spare HP9826 computer with a dead
display along with extra HP9000/300 computers.
Thanks

I've got a lead on one with plenty of accessories but the guy needs someone
to assess a realistic value to the machine, for IRS reasons or something like
that. What could I tell him? He saw the functioning /// with profile I own, so
it would be neat to have a working plus model alongside it.

Hi
Patrick Rigney and I have been working on a program to
transfer disk images to and from a H89/90 to a PC through
the serial port. It looks like we have a working setup.
Here are some of the things one might use this program
for:
1. Boot Strapping a system without any boot disk ( you do
need a 10 sectored diskette ).
2. Archive disk data onto newer media.
3. Transfer disk images over the Internet.
I'm looking for a few more guinea pigs to try it out
on. Right now, it is only working in a pure DOS boot
and not in a DOS window under windoze. If anyone know
what the problem is with windoze and serial port access,
I'd like to better understand it?
The stuff I have includes:
BOOTSTRP.OCL Octal code to cold bootstrap
H89TRANS.COM DOS program to run transfers
H89LDR.BIN Main loader program to run on H89
If you have an extra blank disk, you only need to enter
the BOOTSTRP, from the H89 monitor, once. You can then
make a bootable disk that brings up the transfer program.
The program includes built in formatting so you don't
need to worry about that. The system needs one of the
H89 serial cards. Right now, that is the only access
I've implemented. I currently use the H89's LP: port since that
doesn't require a null modem connection and simple 1-to-1
wiring works from a serial port on the PC. The port on the
PC side is selectable.
Disk image files can be transfered to and from the H89.
These are simple non-compressed disk images. This way one
can often write simple programs to read text files and such
>from the images files. I may add a HDOS file read/write
at a later date.
There are some 9600TPI disk out there ( and I have a couple )
but I've not dealt with these yet. If you have a system that
uses these, you'll need to wait.
I am also especially interested in image files you may have.
This is one of my main motives for writing this. There
was a bunch of interesting things out there that would
run under HDOS. I also have my Forth that runs standalone for
those that are interested. I include a Forth meta compiler
to modify or add anything you want. You can also make turnkey
systems as well.
Please reply if you are interested.
Dwight
