I have just been offered an altair computer, it's been sitting in the back of
a garage, unused for some time.
I don't want to just plug it in and power it up right away do I ?
Inspect -- what am I looking for?
Clean -- best method?
It is described as "not having switches or blinking lights", having floppy
disks, having been used for somthing to do with ham radio.
This is in advance of actually getting the computer,
Greetings to all --
About a year ago, Joe Rigdon very kindly gave me a number of old machines
(thanks, Joe!), among them a Xerox 820. At the time he gave it to me, the
unit didn't power up, but today I finally found the time to give it a
second look. After I reconnected a loose lead inside the box it came to
life! This is my only machine with 8" disk drives, so I'm interested in
finding a good use for it.
I could use some help from the list members, though. I found *no*
technical data via Google, and have *no* real docs for this beast. After
poking at the 820 for a bit, here's where I'm at:
--> The "B" drive is faulty. Disk initialization fails, and it will not
consistently read disks created on the "A" drive. Any pointers on
replacement drives? Even if a thorough cleaning revives this drive, I'd
like to obtain a spare.
--> Assuming I can't revive the "B" drive or find a replacement, how can I
duplicate diskettes? The CP/M utilities all seem to want two drives in
order to do their job.
--> Two of the boot diskettes which I have boot up a pretty normal looking
version of CP/M 2.2, with a normal "A>" prompt, but another diskette
displays the following upon boot:
"Good Day! ZCPR 2.04 SYSTEM READY"
and the prompt is "A0>" (obviously user group 0). What is this "ZCPR"?
--> Some of the utilities on the boot diskettes (FMT, for example) refer to
hard disk drives. What's involved in attaching a hard drive to this
system?
--> The flimsy "User Manual" which I have states that the RS232 port may be
configured to attach to a terminal or to a modem. How?
--> Lastly, does anyone have any documentation on this thing? If you can
part with it, I'd be glad to pay a fair price.
Thanks in advance for any help you can provide. Although this system
doesn't appear to be special or unique, it does seem to be a sort of nice,
friendly critter, and I'd like to put it into use.
Later --
Glen

An interesting early CPM computer, complete with monitor and fdds. AES is
Automatic Electronic Systems, a Montreal company that was founded by
Stephen Dorsey who then sold the company and went on to found Micom.
He put out a remarkable Word Processor/computer called the MICOM 2000
before the Apple got out of Woz's garage. AES must have mfrd. this after
Dorsey sold it. No date given but likely pre 80. Wish I could afford it.

I've managed to pick up a memory-less HP C110 that was upgraded to a
C160. Looking at Kingston's site, they want way too much for new memory
for it. Does anyone have extra memory, or a source for memory? I've also
got an HP Apollo 715/50 - is that memory compatible?
Thanks for the help!

To make this sort of on topic, I'm willing to
trade some classic hardware (various S-100, old
Tandy, old Mac, others...) for one.
NOTE: The watch does not have to be working, just
in good cosmetic condition.
Please email if interested.

Hello, all:
I'm looking for the following book from the early Dr. Dobbs book
series. "SmallWindows - A Library of Windowing Functions for the C Language"
written by James E. Hendrix. The original publisher is M&T Books.
If anyone has this and wouldn't mind parting with it, please contact
me off list. Thanks.

I've found a programming manual for this English Electric
machine. With luck I will eventually get it OCRed and
posted somewhere but if anyone has any questions it may
answer meanwhile feel free to ask.

Hi
I have an Allied catalog that is a couple of years

listed:

Byte Magazine and Infoworld both used to publish figures like this nearly every month or week, respectively, as I recall.
Don't remember what their sources were. You're not the only one who'd be interested, though.
The figure I always heard for total sales of the 4A was 2-3, maybe 4 million. Not sure how accurate that is, as TI had to eat a bunch of returns when they pulled the plug, but it's probably in the ballpark. There are still piles of them around, anyway.

I have a Televideo 912C and a General DataComm Gen Net Terminal Server. I
want to make these two machines talk to each other. I think it would be
really cool to be able to display a Trek game or something. But I have a
couple of problems. First of all, I'm mostly a PC guy. I don't know
anything about these machines. Secondly, I don't even think the ports on the
back of the Gen Net are RS-232C. If they are, there's a protocol problem or
something, because what gets echoed back isn't what I type. (I type several
characters before one is echoed, and the echoed character is usually an
odd-looking non-character.)
I don't know the password on the server, and I don't know how to operate its
control keyboard. Here's something else weird--you have to actually remove
the front cover to turn it on and off!
Here are some pictures of these machines http://mywebpages.comcast
net/fastluck1/Televideo.htm. Check out the terminal--it looks really cool.
Can anyone give me information on operating these machines, or point me in
the right direction?
Thanks in advance,
John

I could use 3 of these power cords. They are just
what I need for my Electronic Associates TR-20, TR-10
and the ATC-510 flight simulator.
I found the Alpha 663-7082 in their catalog on page 385.
$4.85 each for 1-24. $4.41 each for 25-up.
http://www.alliedelec.com/catalog/pf.asp?FN=385.pdf
They say "There is a $25.00 minimum on all on-line orders."
"Orders that total less than $25.00 may be subject to a
handling fee. The amount of the handling fee will be the
difference between $25.00 and the total amount of the order."
"The shipping cost on any order will be determined at the
time of shipment. All shipments are F.O.B Fort Worth, Texas.
Shipping method, in most cases, is the customer?s choice."

I have volume 2 of the 1984 databook but it contains a complete index and PN reference and there's no mention of either part in it.

Hi
Well, it looks like I was right after all. The part numbers
I posted were correct. I could use a couple of these cords
myself. I have a few but not as many as I have things to use it
on and some cords are in poor shape. I'm not sure If Allied
has a minimum order ( but I think they do ) but I'd be willing
go in with someone else on a purchase of at least 3 of these
cords. Their on line is listed as www.allied.avnet.com.
I haven't checked it out yet but if there is some interest
it might be worth it. The shipping will be high compared to
the cost of the cords but that is life.

Picked up a Gateway 15" digital flat panel display at auction on Thursday
and need the video cable and ac adapter for it. Gateway was no help both
online and I went to one of their local stores (they do not carry parts).
During a google search I did find these part numbers cable = 8003275 and
adapter = 6500322. no luck on ebay either. Anyone have clue? Thanks
Ouch! Good luck. I wonder how rare one of those are. I've heard of them
(I think), but I'm pretty sure I've never seen one for sale. Depending on
how badly you need the data, you might want to consider looking for a
professional data recovery service that might have a drive (unless you're
lucky and someone on the list can do it for you).

Is it normal for a Variac to hum when it's plugged in?
If not, any ideas why one would do so?

I would offer to repanel that wall for them (even the entire room to make
sure it matched) if it meant laying my hands on one of those.
Is the family selling the house? If so, stay in close contact, and even
talk to the realitor and see if you can arrange something with the buyer
to take custody of the machine.

Those drives must be from an IBM control unit, such as a 3174, since I know
the drives in it say "1.4M" next to them.

I finally got serious about my Commodore LT and did some major Googling
thru the NGs. Following some hints I found, I got what I think is the pinout
for the 8pin mini-din power plug on the Zeos site. Sanyo appears to be the
mfgr. Anyone on the list have one of these beasts ? 3 of the pins take 15v
and I'd like to find the amperage requirements.
