As I and several others discovered today (Friday, 9-Feb-1990), Halted has NO more 3B1 power supplies; they still have a quantity of 7300 power supplies. I even checked their warehouse. Sigh. Seems "someone" bought a very large quantity recently. I'm going to check out a few other surplus houses while doing my marketing Saturday and will report back any findings.

Sigh. No more 3B1 power supplies are to be found in ANY surplus store in
Silicon Valley; all places from San Jose to Cupertino to Milpitas, Fremont
and up to Oakland were checked (other people were looking, too, per reports
I received by e-mail).
However, we (the AT&T Users' Group secretary and I) did find the following
items at Computer Surplus Solutions (also known as "Weird Stuff Warehouse"):
1) UNIXPC Foundation Set Version 3.51, brand new with original shrink wrap,
manuals, etc. Price sticker was $225. One (1) copy only (located in
the front counter display case).
2) Mouse balls for UNIXPC mouse. These are NOT your everyday "standard"
Logitech balls ... these are specially weighted (much, MUCH heavier than
standard mouse balls) and are the ONLY ones that work properly in the
UNIXPC mouse. $1 each. Located in a counter-top display case near the
front of the store. Finally, at last, my eunuched UNIXPC mouse is
"whole" again! :-)
3) Motorola 6300 system, complete with RS-422 display terminal. $1,400.
This machine is object-code-compatible with the AT&T UNIXPC and the
Convergent Safari 4 and MiniFrame series.
4) a few UNIXPC keyboards with cosmetic flaws. $20 each. No mice and no
cords.
That place is incredible; 150,000 square feet of floor space, with 40' high
ceilings. They also had some LARGE AT&T monitors but I have no idea what
model numbers. If you want to call or visit them:

Milpitas, CA 95035 408/434-0168
The DeAnza College (Cupertino) computer flea market had a few vendors with
some misc. UNIXPC software (dBASE III, Supercomp, etc.) for around $75 each,
but the flea market was closing as we got there and didn't have time to check
it out completely; perhaps next month (2nd Saturday every month in the Student
Lounge).

The 3B1 supply is 245W with 5A at 12VDC, the 7300 supply is 195W with 3.5A
at 12VDC; both supply 20A at 5VDC. The -12VDC comes in several variations
depending on revision level; doesn't seem to make any practical difference.
Other differences:
1) 3B1 powers its hard drive directly from power supply; 7300 powers
its hard drive off the motherboard.
2) different model of TEAC floppy drive (3B1 has spring-eject, and
seems quieter)
3) 3B1 keyboard has a "writeable" strip above function keys
4) 3B1 has "hump" at case center for full-height hard drive
5) 3B1 has one fan, (most) 7300s have two fans

Which reminds me, I have a 7300 and a 3B1 power supply that I'd like to stick in it. I know instructions on the necessary changes have been posted but I can't find any copies in my archives.

this was a running change in production; one of my 7300s has both, the
other neither.

Perhaps this was not a difference between them as much as a design change. The floppy disk is in a rather awkward position, and the spring eject is a very welcome feature. I wish my older 7300 also had it. -- Tom Tkacik GM Research Labs, Warren MI 48090 uunet!edsews!rphroy!megatron!tkacik Work Ph: (313)986-1442 "Csh must go. This is non-negotiable!"

Interesting that this subject should come up right now. Over the weekend my 3b1 seems to have lost its power supply. My clues? The entire thing just died, I was out of the room when it happened but the entire machine is dead. No fan, no video, nothing. Do 3b1 power supplies have a reputation for failure? BTW, have your every tried to find someone to fix a 3b1? It ain't easy. Here I am in the heart of Silicon Valley and people act like my machine is from another planet! "Is that a 6300?"

I've been dealing with these people and the work and prices are good *BUT* they are extremly disorganized. My experiance goes like: I sent them a 67meg miniscribe in December, along with a check for $250.06+tax. They returned the disk and check in january, with a note (written in magic marker) that said only "Sorry, We can not fix your disk?". I called them, and was told that they were out of the parts when they sent the disk back, but they have the parts now. I returned the disk to them, and I'm waiting for it now, two months after I sent it to them originally. They told me that its been shipped, so I should get it this week. They were very courtious over the phone, and the price is right, so I post this experiance as a warning rather then a flame. I've heard good and bad reports from others, and as far as I know, everything always works out in the end. Anyway, here's the info : ***** REPOST FROM OCT 6 1988 ***** PRICES HAVE CHANGED ***** Well, I just got a new unixpc motherboard back from San Leandro CA, after shipping my old one to them for repair, and thought I should relay to the net how everything went. First, I'd like to thank Gary Butler for posting the note describing all this (excerpts below), and also Ben Wollberg of AT&T who was very patient, and informative on the phone when I called. Here's the deal, if you have some flakey/bad components in your unixpc, and you want to swap them out, you can send the defective ones to Ben, and he'll send back refurbished ones that work. The price list is as follows: (this is from Gary's article) > Motherboard 120.75 Repairable [ ^ this price has gone up to 160.00 ] > 300.00 Replacement Price approximate > > Power Supply 45.00 Repairable > 75.00 Replacement Price approximate > > Hard Disk 115.00 to > 200.00 Replacement Price approximate > > Floppy Disk 45.00 Repairable > > The repairable price is just that, all other prices are exchange but the > component you are bringing in is unrepairable, such as the motherboard > burnt up because the fan failed. > > All components and parts carry a 90 day warranty. > > They also have 64K and 256K memory chips that you can buy for replacement > or upgrade.

My motherboard was a very old 0.5M board (fully populated 64k memory chip set), that was not working properly. The new motherboard came in with 1M on it (for which I did not pay, it was potluck) and had some white wires on it which presumably are the latest and greatest hardware upgrades (I have not confirmed this). If I had the time, I would have soldered in sockets in the other half of memory, and upgraded to a full 2MB on board, and put in the P5.1 upgrade like I had before! The entire exercise took about 10 days (I mailed it in on a Sat, and I got it back a week later on Tues), and I think I got a great deal. Feel free to mail me if you have any other questions. -Craig Votava [att!]looney!cmv ************** END OF REPOST ***************** ################################# :alex. #Disclamer: Anyone who agrees # University of Maryland Baltimore County #with me deserves what they get.# alex@umbc3.umbc.edu #################################

How DO you go about getting a 3b1 fixed?
Ed and I discussed his problem today by phone, and I invited him to the next
meeting (next week, 28-Feb-1990) of the AT&T Users' Group, South Bay UNIX
(meeting in the AT&T site at 1090 E. Duane Avenue in Sunnyvale at 7PM; there
should also be an announcement in the San Jose Mercury News' COMPUTING CALENDAR
this Sunday; forget the announcement in COMPUTER SHOPPER ... that one is all
screwed up).
An announcement will soon be made publically for "A Small Computer Repair Co."
whose charter is to fix and repair AT&T 6300, 7300, 3B1, UNIXPC, and like
computers. The AT&T San Leandro (CA) site is being closed down, so if you
used to send your computers there for repair you'll want to keep an eye out
for the ``ASCRC'' announcement; that San Leandro site is(was) the world-wide
AT&T repair center for 6300, 7300, 3B1, UNIXPC, and like computers.
