Well St225 is MFM so the card is either a host to MFM bridge or SCSI(SASI)
to MFM bridge.
The real answer is a part number on the card like WD1002-HDO (host interface
number). Someone else may be able to confrm if the SHD is SASI or at that
time early SCSI.

(somewhat off topic... only 5 or 6 years old and a PC at that :-)
Well as I mentioned in that screenphone thread I bought an IBM 730T.
There are lots of them on ebay right now at prices which make me wish I'd
not bought that ill-fated DTR-1. This is a tablet type pen-based computer
which has 8 megs RAM built-in, 3 PCMCIA slots and 1 RAM card slot which
collectively take up the space of 2 type-III slots. So if you put in a
hard drive you have 1 type-II slot and 1 RAM slot free. (I don't know
if the RAM slot is what is known as type-I, but the pins are arranged
differently and it takes a DRAM card... I'm hoping those cards are
interchangeable regardless of manufacturer but I'm not sure. IBM intended
a 4 or 8 meg card to go in there.) When you turn it on, there is no
BIOS setup screen that I have found, it just immediately proceeds to load
DOS off the 105 meg hard drive that came with it. Mine came with nothing
other than command.com loaded on it so I have no way of putting other software
on right now. Floppies for them are rare and expensive. I tried borrowing
a coworker's laptop last night to transfer software to the hard drive, but
I couldn't make it show up in any of WinNT, FreeDOS or Linux. So I will
have to either buy a floppy or a PCMCIA card drive for a desktop PC I guess.
I want to try and put Linux on it and get X working with the pen. So if
any of you have any of the following for sale or trade:
PCMCIA hard drive with more of DOS installed so I can use intersvr at least
or Linux
a clever substitute for that
PCMCIA slot for a PC
floppy for the 730T
other ideas on how I can try to install Linux
... let me know. I have quite a significant pile of junk^H^H^H^Htrading
stock. Hmmm, matter of fact I think I'm going to go add a list of stuff
to my home page right now because it's accumulating fast and I need to
start losing some.
I don't know even if I get Linux onto it, if the fact that DOS boots without
any card services being installed, implies that Linux will also see the
hard drive as an ordinary one or if I'm going to have to build a kernel that
has the PCMCIA support compiled in rather than as modules. I'm beginning to
wonder if the hard drive itself is special. Since there is no BIOS setup
could I get it to boot from a different sized drive... and maybe also
this accounts for why the hard drive didn't look normal to the other OS's.

That _is_ a good price if it was for the lot. If anyone is looking for
a similar item, I have a box of Sony MP-F11W-72 drives, 720K DSDD 3.5"
floppies for various Tandy boxes, including the Tandy 1000. One catch: they
don't have a power connector. They draw power over the 34-pin data cable.
Typically, floppies have grounds on the odd pins; this one scopes out thusly...
1 NC (uninstalled jumper at RJ1 (GND) and R1 (?))
3 NC (uninstalled jumper at RJ3 (GND)) (FAQ claims +5VDC)
5-11 +5VDC
13-19 GND
29,31 NC (uninstalled jumper at RJ7 (GND)) (FAQ claims +12VDC)
33 NC (FAQ claims +12VDC)
(cf. the Tandy 1000 FAQ - http://www.oldskool.org/~tvdog/1kfaq.html#II.C )
There is a space for a power connector, but it is not installed. If you feel
like migrating a connector from a dead floppy, it's doable, but for non-Tandy
use, a modified cable might be the better solution.
I got these from the Dayton Hamfest in a "you want one, you take the box"
deal from the local Radio Shack guys that used to have a great booth in
the white tent in the corner of the flea market. I will never use more
than one or two of them. Now's your chance to stock up on bizarre Tandy
drives.

All,
At the Texas Thrift Store in San Antonio, loop 410 just south of
Ingram, I found:
AT&T 6300 and Xerox box - these two looked identical except different
color schemes. Both $6.95, "as-is" and the Xerox says "works". Xerox
claimed to be made in Italy, I didn't check AT&T.
Apple IIGS - mmmm...$13.95? I didn't write it down. "as-is"
Franklin Ace 100? - ... $6.95?? "as-is".
All boxes were seperated from monitors, keyboards, cables, manuals,
software - bare boxes only. I did not spot any such peripherals which
looked at all related to any of the above, but didn't look very hard.
If anyone is interested, email me offline and I'll buy, pack, ship,
and let you know how much it cost to do all three. Hopefully, you'll then
send me a check for that amount...

PS are announcements like this of value to anyone? Should I continue them?
Move them to the auction-announce list? Comments offline preferred, online
OK if they are of general interest.

More realistic than any single "bluebook" would be to call up dealers
in such equipment and see what they're willing to offer.
The classic place to begin such a search is in a long-standing
minicomputer rag called _Processor_. They're mostly PC-clone ads these
days, but they still have a few pages dedicated to DEC and Data General
equipment, and there are certainly many outfits in there that'll be
interested in quality (i.e. not PC-clone) terminals, network equipment,
printers, etc.
See http://www.processor.com/ for their on-line presence. It's expanding,
though it's still not nearly as good as the actual printed edition.

Actually there is a computer blue book. It might cover the Wyse terminals
but it is more PC based. It has some mini stuff but I doubt the Sequent,
routers, bridges UPS etc. Pawn shops use it to evaluate what they will loan
on equipment. They are published by Orion Research Corp. in Durango
Colorado. It is published yearly and cost about $150. It is actually blue
colored.
I could help evaluate it if they want to contact me off list. I suspect they
would be shocked at the actual valuation. Of course it depends on the age of
the equipment.
It might be a candidate for a rescue though. Is anyone on the list running a
Sequent.
Paxton
Can anybody direct me to one (or a few) good websites or ftp boards that
have software for 68k-based Macs (one that has Smooth Talker, & a
Stylewriter II driver would be nice).

It was fun! A boxed coco2 and mc-10, and letsee... a model 4, a model 1
L1, a model 1 L2, a Holmes Expansion Interface, 2 disks, a light pen, and ;)
the plug&power controller with docs and cassette software. Non Radioshack
stuff included a prettily outfitted Atari Portfolio, a Covox voice master
again for the atari I hope, an Epson hx-20, and ;))) an Applied Microsystems
diagnostic cpu emulator with a 6809 pod and documentation.
I drove back down there later Sunday and didn't see anything more than I had
on Friday, and am in some respects glad. This haul will take awile to
assimilate....
Cheers!

It is an 1802 CPU. the 936 is the 36th week of '79 most likely.
Nope, not any of the 1802 SBC I know of and the connector was not typical
of hobbiest class machines. My guess is a custom app.
