Well,
I feel a bit like Michael Jordan and Magic Johnson, but "I'm back..." I've
been fighting a few demons, some still unsuccessfully, but I feel like I can
devote more time to my beloved hobby now...
The collection has grown a bit, and shrunk a bit :-), some given away, some
sold, some gotten free, some purchased (are there any other ways? :-)).
Some stuff will continue to leave over the next few months as I settle down
a bit ...
So, to keep on-topic, what have I gotten lately?
- A SWEET Heathkit H89, with manuals, disks, etc. (Yes, I'll be contacting
Tom off-list). This was bought from a man in Kansas, who was the original
builder, and even included the original receipts! He kept great records,
and passed it all on to me. Cool! Now I just need to find some blank 5.25"
hard-sectored disks to make backups of what he sent me.
- A couple of Motorola Single-board computers, 6802D5 and 6800D2 I believe
- An Intel SDK-85 -- Needs work on the keypad, but OK otherwise
- A Xerox 820 (CPU/Monitor, Keyboard, 5.25" floppy drives), with
disks/manuals/spare parts.
- An Apple IIe "upgraded" to a IIgs -- This is basically a IIe case, but
with a ROM 01 IIgs motherboard, and a special back plate for the IIgs ports.
Also replaces the IIe logos on the case with "IIgs" ... Very nice!
- Various Apple II stuff -- CMS SCSI cards w/ manuals and disks, A "Quickie"
hand scanner for the IIgs w/ manuals and disks, RAMfast SCSI card, Zip GSX
accelerator for the IIgs, Syquest removeable 44MB drive for the IIgs (not
Syquest drive, but uses Syquest 44MB media), High-Speed SCSI card, various
software
- PowerMac 8500 w/ 500MHz G3 (1MB cache) upgrade -- Yeah, not vintage, but a
sweet deal! :-P
Anyway, thanks for letting me ramble ...

I am trying to get a TRS-80 Model III working. When I turn it on the disk
drive spins for a while looking for a disk I presume. All I get on the
screen are wispish diagonal lines as if the horizontal hold is all
whacked.
I managed to unstick one of the video adjustment knobs on the left
underside but all it does is affect the brightness level. The other one
requires a screwdriver to move at all (shimmying it up and down) and does
not seem to affect the display. I haven't opened it yet to see what
adjustments are inside. I'd rather not, but there don't seem to be any
adjustment pots accessible from outside the case.
What's weird is that I have access to a bunch of TRS-80 Model 3's here at
the ACCRC and pretty much all of the ones I have played with so far are
basically "dead" in this manner. The one I'm working on just came in
today and is in the same state. Also, the video knobs on the left
underside are all stuck on everyone I've tried to get working. What is
the deal with that? Do they get rusted over time or something? Very
annoying.
The fact that the disk drive spins up when I turn it on is a good sign I
hope.
Any help on this would be appreciated. I know next to zero about the
TRS-80 series.

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.

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?

No - the RRD50 is the tabletop device with a pop-up lid.
I'm pretty sure it is slower than the (later) RRD40. Both
used the KRQ50 Qbus interface, although the RRD40
was also available with an internal converter board that
turned it into a SCSI drive. Quite popular in the early
VAXstation 3100s, IIRC.
I have an RRD40 right in front of me and (again, AFAIK)
it can be used as a boot device but unlike the RRD50,
it's only dog slow :-)
The RRD40 and RRD50 both came from Philips (I think).
Both used their LMSI(??) interface. The converter board
that helped the RRD40 do SCSI was reputed to be "not that
good". Put another way, the RRD40 has a bunch of quirks.
I'm not in the least suprised that an AlphaStation turns up
its nose at it. (I vaguely remember some alpha console
command that can tweak the SCSI interface - perhaps
you can persuade the two to get on that way ... assuming
you can find the details which I've helpfully forgotten!)

While I would agree with the recommendation to go with a modern
OpenVMS variant (V7.3 or V7.2), the VAX 4000-200 was in fact
supported as far back as VMS V5.4-2. TF85 support may not go
back quite that far: I don't have the old VMS SPDs to hand.

Isn't the RRD50 the one with the wierd "pincer" caddy? I've found it to be
very bootable and useful. Sure it's *SLOW*, but hey, the important thing is
that it boots! OTOH, if you try and hook it up to something like an
AlphaStation 200 4/233 I know for a fact it won't work.

The RRD50 is only theoretically bootable ... it's less than a 1x drive
so it takes sometime longer than the current age of the Universe to
actually boot any OS ...
An RRD42 or later does quite reasonably.
Antonio
The TF85/TZ85/TK85 are all the same basic drive, with
DSSI/SCSI/STI interfaces respectively.
Everything up to the TZ87 can read TK50 (CompacTape)
and TK70 (CompacTape II) carts.
The TZ87N was a cost-reduced TZ87, some of the cost
saving coming from dropping the backwards compatibility.
Beyond the TZ87N, nothing (AFAIK) can read TK50 or TK70
carts.

I'm not sure you'll be able to even run V5.5-4Hx (I think that's the high mark
for V5.5 and I'm not sure what the 'x' was), and I'm pretty sure you can't
run plain V5.5. You might need to go with V6.0 in order to have VMS support
your hardware. If you can get someone to build you tapes, I'd recommend
getting V7.2 or V7.3 instead of earlier versions if you can, as all the doc's
are available online.
IIRC, the TF85 can read TK50's and TK70's just fine, however, you can't
write them. Once you get the system up and running you'll probably want
some Compact III DLT tapes (or does it require Compact II tapes).
I take it this is the first VMS system you've owned? If so you'll probably
find some useful pointers in the VAX section of
http://www.aracnet.com/~healyzh/decemu.html

More or less
TF = DSSI
TZ = SCSI

You should be able to read TK50 and TK70 tapes on a TF85.

I need to kludge a momitor for an M24 (which is

I remember the machine from student days, and the

Any ideas?
