Is the AT&T 6300 a rebadged M24? If so, the D connector also carried power
for the monitor (which had no separate power cord).

It has two nonstandard features:
* High scan rates, leading to 640x400 resolution
* 25-pin "D" connector instead of a 9-pin
I know we used some Aydin 19-inch monitors on M24s back
in 1986, but which models (and what scan rates) I can't
remember.
I did write some code to toggle a bit in the M24 and
cause the screen to degauss, though. One of the Olivetti's
enhanced features.

I managed to grab a whole bunch of UNIBUS boards without knowing what they
were today, and found out that they are basically the boards to an 11/40
CPU. Unforunately, I didn't see the rest of the CPU, or the M7237 board
(is it an optional board?) or a backplane or... just the boards:
M7231 KD11-A 11/40 data paths module
M7232 KD11-A 11/40 micro word module
M7233 KD11-A 11/40 IR decode module
M7234 KD11-A 11/40 timing module
M7235 KD11-A 11/40 processor status module
M7236 KT11-D 11/40 memory management module
M7238 KE11-E 11/40 EIS board
M7239 KE11-F 11/40 FIS control
Also I found a pair of 16KW _core_ memory cards (quad width). I separated
one board, and the cores are IMHO absolutely beautiful.
Two questions:
1) If I could find a backplane and powersuppl(ies), (and some peripheral
stuff), is this enough to make a functional CPU?
2) Does anyone want this stuff? I want to definately keep one of the core
memory boards, but the rest of it doesn't do me a whole lot of good. I'd
like something interesting in trade or some money over shipping costs if
so.
I'm looking for a PDP-11/73 or -11/23 CPU to upgrade my LSI-11/2 :) along
with memory for it (I have 8KW I think), and/or an RQDX1/2/3 or similar
controller so I can attach some real (non-emulated) drives to it.
I don't have anything to test these boards, so I can't verify that they
work, of course, but they look in very good shape... no burn marks,
oxidation, not much dust, etc.

Anyone who would like a Tandy 1400FD should contact Elizabeth at
<fefraser(a)yahoo.com> before mid-October. She is here from Guyana and
brought this machine along to give to someone who would want it for their
collection.
I tried to get it to a collector in Argentina but he couldn't afford the
shipping.

7 inch snowblower? That seems sort of small to me...

I have a spare manual on the H89 (yours for no charge), and a bunch of other
H89-related stuff ... Contact me off-list, and we can work out the
details....

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.

Sorry to use the list for this, but I lost some older emails, and no longer
have the email adresses for you...
Gene/Toth,
Remember those PS/1 diskettes I told you would be coming 4 months ago??
They're finally sent (thankfully, your mailing addresses were stored
separately from my email), along with humblest apologies... You may flame at
will...
John,
Hard to believe I am so inept as to still owe you for the DEC LN03R stuff
you sent eons ago.... Do you have a PayPal account? If not, the money will
be sent in tomorrow's mail... Again, feel free to flame....
Rich B.
