Hi,
Can anyone explain to me what make a PC recognize whether there's a
keyboard attached or not? Is it something as simple as current/voltage, or
does the bios actually have to receive some kind of recognizable signal
>from the keyboard? I have a vintage ThinkPad that doesn't like my external
keyboard, yet it works fine with other external keyboards that I've tried.
Mine works fine on another system...
As always, any help would really be appreciated,
Aaron
It seems that nobody has noticed that on ebay is going for sale an IBM 604
calculator. This is the oldest electronic machine I've never seen for sale,
and if it weren't for an ocean dividing me and it...
The IBM 604 was launched in 1948, and kept in commerce up to about 1953.
It's about 2000 pounds total, 1400 tubes, a programmable calculator reading
programs out of an punch reader (offered in this sale).
There is a specimen of this machine at this dutch computer museum, with a
photo of the little thing:
http://www.wins.uva.nl/faculteit/museum/604.html
This is how IBM depicts the 604 in it's own history:
http://www.ibm.com/IBM/history/timeline.nsf/products2
The specimen on ebay has the 521 card punch/reader. This is the description
of the seller:
>IBM 604 weights 1300 pounds. LxWxH 52 1/4" x 31" x 60".
>IBM 521 weights 740 pounds. LxWxH 41" x 25 1/2" x 50".
>They require 220 volts & draw 36 amps running & 30 amps
>at idle. These 1950s era EAM machines have around 1,000
>glass tubes & will heat up a room quickly. Sold as is,
>may not be complete, some manuals but no parts catalogs.
>This pair probably has not been used in 20 years. I repair
>IBM card punches but not these babies!
The machine is in Santa Fe, Texas, and the current bid is $224,
ridiculously low if you consider that a single IBM tube of that series has
been sold for up to $170 on ebay, and there is one currently going for $50.
There are 1400 of them in the machine, and if somebody here does not act I
am afraid the machine will be bought and cannibalized to sell pieces!
There is still 1 day, 5 hours to the sale close! This is the ebay URL:

PS please let it be clear to anyone that I am not the seller; I just would
like to be the buyer, but I can't becaus of obvious distance problems!
Hi Everyone!
Just an update on the great DEC/Compaq collection that arrived last week
>from New Hamsphire. Over 90,000 lbs of historical DEC hardware arrived
thanks to a generous grant to cover shipping from Compaq. Mike Zahares of
TransTech, our North American Van Lines agent, did his usual brilliant job
of making sure everything was handled with kid gloves over the 3,000 mile
journey!
Thanks to the many volunteers who helped in the receiving of these rare
artifacts, they now have a permanent home (the artifacts, not the
volunteers! Although some volunteers _do_ seem to live here!) :_)
Special thanks, therefore, to: Lee Courtney, Bill Pitts, Bobbi and Steve
Rabinowitz, Charlie Pefferkorn, Jake Feinler, Mark Schaeffer, Ron Mak, Rob
Shaw, Ken Sumrall, Al Kossow, Grant Saviers, Joe Frederik, John C. Green,
Sam Ismail, Mike Baxter, Eli Goldberg, Ed Thelen, John Francis, Wayne Chin,
Bob Joslin, Thomas J. Ackermann, Mike Zahares, Len Shustek, Mason Brown,
Bud Warashina, and LaFarr Stuart. Forgive me if I have forgotten anyone!
And History Center staffers Karen Mathews, Wendy-Ann Francis, Jack
Hotchkiss, and Chris Garcia all pitched in and made sure the project went
off without a hitch.
Without all the hundreds of hours of help from these volunteers, who
believe so firmly in the preservation of computer history, we could not
have done this!
Pictures of the arrival are available at:
http://www.computerhistory.org/events/latest/
Note: photos of actual machines will be posted at this same URL on or about
January 13th so check back then--we are creating a new exhibit on the DEC
contributions to computing that opens to the public on that day!
Thanks everyone for your support! Hope to see you at the Center or on-line
soon...
Sincerely,
Dag.

OK,
First, does anyone have docs/software for and FPS 5300 Array Processor? I
know what it is and what it does, but I need more than that.. lol... Second,
anyone have manuals and software for the Professional 325? I need them
badly... Third, same for Honeywell DPS-6/54... Fourth, I need an Interdata
7/32C front panel. Fifith, an Interdata card reader. 6th, an Interdata line
printer. 7th, some Data General binders circa Nova 1210, if such critters
exist, to house my docs for said machine. 8th, advice on whether or not I
should try to restore a VAX 8650, its currently upside down and cardless,
but I have more than half of the cards and it doesn't look rusty or
anything.. also 2 Unibus cabinets, 2 SBI cabinets, and the FEP..

Do you think you could make a copy of the manual for the DSD-880 for me?
I'll pick up postage, plus a little extra for your time . . . .
You sure make me wish to hell I lived in the pacific northwest. I really
would have *loved* to grab some of the stuff off of the 'LIST'.
Thanks
Jeff

Can you format one 1.44MB down to 720K? Early Laptops had 720 K diskettes.
Should be a format switch like / 720 or s:720

Hey,
Anybody familiar with the Zenith Data Systems line of Honeywell Bull
laptop computers? I just recently got one from a friend, complete with an
inkjet printer. I have pretty much all the specs/manuals that originally
came with it. No software. I booted it up for the first time and got into
the BIOS and fiddled with it enough for it to boot. It had DOS installed on
it. Does anyone know if that is the original OS, if not what was it? Now
here's the problem, when it boots now I can't get into BIOS or even into the
system monitor program. I have tried boot disks, nothing. I can't get it to
read the disk. hard disk or floppy. The boot disks I have tried have all
been 1.44 mb, do you think that maybe a low density disk would make a
difference, and if so does anyone know where I can get my hands on one?
Anyone have any ideas? Sure could use some advice!
Thanks,
Mark Belles

My concern is that something heavy may have been left on this thing for
multiple months/years and bent the plastic over time. I don't know this
for certain, but when I got home, the cover was broken (crack in the
clear acrylic panel at a corner, small bits broken off the opaque cover
adjacent). I'll disengage the heavy spring from the front ratchet and see
how freely this platten turns. For my tests last night, I was turning the
platten manually with a light grip on the feed knob and, depending on the
angular position of the platten, sometimes the platten would turn, other
times, my hand would slip on the knob. With the plattens exchanged, the
better unit turns easily and freely about the whole revolution and didn't
miss a single line feed in several feet of tests.

It is not stickiness on the ratchet teeth. I remove the platten and cleaned
each tooth with a cloth and blunt stick. It could be uneven wear.

I saw that the linkage could be disassembled, but at least this way, I didn't
have to readjust the tolerances. Fortunately, I think this is a one-time job.

Got that already.

Easy enough.

An important tip. Many thanks.

I don't know of any simulators for the Univac 36 bit series. It would
be an interesting project, though. I wonder how much documentationf or
the original ERA machine still exists.
Exec 8 or it's descendents may be tough to find, though.
