After digging into the boxes I got Thursday I found over 150 3.5 FD with
various Next software on them and 12 CD's with Next software. Also I got 10
optical disk in cases for the Next along with a Pinnacle Micro external SCSI
optical reader, model PMO-650. Got two sound boxes that were in parts and
need to be repaired. Will put together a list of the software and send it
later.
Just to clarify, the following is the pinout of a terminator that works
with an
RL01 drive. It *should* work fine with an RL02 since the same interface
card works with both, so unless there's some oddity about the RL02, this
should do the trick:
Opening the pack, there is a single large resistor pack, 40 pin.
Looking at the back of the resistor pack (i.e. looking at the outside of
the RL01 drive connector)
the pack is marked with pin numbers; pin1 is at the bottom right, pin 2
is at the top right, pin 39 is at the bottom left
and pin 40 is at the top left. Pin 39 has been cut. All other pins are
connected.
The resistor pack part number is 13-13242-00 SSM 7934
Neither side appears to have commoned pins.
Each opposing pair of pins has 160 ohm between them (i.e. between
pins 1-2, 3-4, 5-6 etc.) Obviously 39-40 is open circuit.
I think it would be easy to make using a 40 way pcb-mount idc header
with some shrink sleeving as the terminator isn't subject to any
mechanical strain
(unlike the cable). You could then attach this to the 40-way IDC socket
which normally
plugs into the DEC connector on the inside
of the drive, and you would then just be using the external DEC connector as
a seal to stop dust, etc from entering the unit. Even though the RL01
seems quite
tolerant to the ingress of dust, (some of the maintenance procedures
involve running the
drive the the covers off) it doesn't do to take any unnecessary chances
with kit this old.
Hope this helps,
Francis

Hello!
I'm currently trying to make an old HP 9000/310 machine work.
Some information about the machine and the status of the
"project" can be found out at:
http://paranoia.rulez.org/~rumi/hp310.html
What I currently need is either a way to crack into the
HP-UX that is already installed on the box, or a floppy
set (== images which can be written to floppies) of HP-UX
that would run on this machine which sports a Motorola
68010/10MHz CPU, 2MB RAM, and a HP9153C 40MB HP-IB hard
disk drive / 3.5" floppy drive combo.
If you have such floppy images, or could help me with any
software, documentation, or information regarding this system,
please don't hesitate to contact me via email.
If I succeed, I'm planning to put a nice webpage together
about the system, with pics, history, infos, etc.
Thanks,
Szabolcs Rumi

Hi Patrick,
I am very interested in the 11/40 board set. And if you want to get rid of one
of the core boards, that would be fine too, but not a requirement. I happen to
have an 11/23 CPU board somewhere, which I would be happy to trade you
along with that RL02 terminator for the 11/40 boards (and possibly one of the
core board sets).

Yes, I remember these. If you looked in the end of the remote, you
could see the metal rods (one for each button). The end of the remote
had a screen covering it. We found that you could use a belt buckle
as a remote, but the results were pretty random, but when you want to
confuse people that was enough.
I always found the high-pitched ring from the striker hitting
the metal bars annoying.

Check out the DEC Enthusiasts Club at http://www.dittman.net/
I guess the magic search key for Google is CP/M and Z180.
Wow, a boatload of stuff.
Came across schematics for a P112 board, SB180,
others, and BIOS listings for CP/M customized to
these boards, and lots of other goodies.
Does running 10+ year old software on new
homebrew hardware count as "half-classed"
(or maybe just half-assed) classic computing?
Maybe we need a name. I nominate: Repliputing. :)

I acquired a Heathkit H89a this last Saturday at a local hamfest, but it
did not come with any manuals. Does anyone have one that I can copy
and return or which you would be willing to copy for me? Or better yet,
is there an extra copy which would be available for a small cost?
Also can someone expound on this computer?

Hello,
Could someone with a more comprehensive list of Hewlett-Packard
part numbers give me a description for part number 98261-66513?
Thanks!
