Well, the Univac III is back: UNIVAC III Computer (In Storage since 1975),
eBay auction Item # 2733726990. This time the starting price is $7,500 and the
buy-it-now is $11,000.

OK, somebody, jump right on it! :-)
(Not me, I'm into LITTLE computers like PDP-11's and VAXen, with an occasional
side dish of 6502 or 8085)

My friend and I have come across a large stock of working ZX-81
computers that are missing keyboards. And a stock of others with bad
keyboards.
These are a lot from a former Sinclair Repair Center.
We'd like to get these working 100% again for sale along with the
remainder of the ZX-81 kits from Zebra Systems.
BTW... Stewart only has a couple hundred left, and when they're gone...
that's it!
Does anyone know of a source for these keyboards, or know of a company
that could make them up?
I have some samples and a schematic of the matrix so this shouldn't be
impossible.
We also have a cache of spare parts (Z-80's, ULA's, RAM chips, etc...)
for these units.
Also, we have a large collection of vintage New Old Stock TTL parts. We
are inventorying what we have now, and will post a website with part
numbers and quantities available.
They've been well stored, and seem to be in great shape.
We also found a small stock of Relays, and other parts. Those will be
listed on the site as well.
It's fun playing with a ZX-81 again. I dug out my TS-1000 and found it
didn't work anymore. When we opened it, we found that the Z80 had a bent
pin. And over the years it stopped making contact with the contact in
the socket due to movement of the parts and corrosion.
Once we bent the pin straight and reinserted the Z80, it came up like a
champ!
And... We also got my Coco III fixed. It came up with a pink screen. We
desoldered the 68B09 and put a socket in it's place. I stole a 6809E
>from a Coco 2 and popped it in. Voila!
It now works!
Computers in the old days were a lot more fun!

Can anyone help me with a simple link to an assembler / linker for a
Pentium III / Pentium 4?
I am attempting to use the EMEM.DLL (Emulated PDP-11 Memory)
under Ersatz-11, but I am basically a dummy when it comes to using
X86 code, especially finding a pair of suitable assembler / linker programs.
I downloaded the Watfor programs, wasm.exe and wlink.exe, but I am
not able to assemble the original file, EMEM.ASM at this point.
In case anyone is interested, the EMEM.DLL under E11 provides access
to PC RAM via emulated PDP-11 hardware registers. The current version
which I have been using allows up to 8 MBytes, but I want to increase that
to about 600 MBytes so that I can write a faster sieve program for Prime
Numbers which looks like it runs in a PDP-11. If I can get the test version
to run fast enough on a Pentium III, I will try it on a Pentium 4 with 4
GBytes
of memory and see if it is possible to sieve the primes up to 10**18
(essentially
a 64 bit sieve program) in a reasonable time (i.e. less than 1 year!).
Sincerely yours,
Jerome Fine

The thought occurred to me that it might be nice to have the
floating-point option in my PDP-11/73. Since I haven't got one, and
don't fancy paying the $500 or so that some online sellers seem to be
asking (do they really expect to sell *any*, never mind at that price?),
I was wondering how easy it would be to implement in an FPGA as was
discussed at length earlier in the week.
Feasible, or a complete waste of time? Presumably I'd need software
written to make use of the floating-point hardware anyway...

I have a Mouse Systems M4 model optical mouse that came with my Amiga 3000 but does not have the special mousepad needed for it, any way to fake one of those pads?
The only other available mouse I have is for the A1000 and has an angled connector that won't fit unless I jack the A3000 case up a few inches.
How well did the M4s work anyway? I did plug it in to my machine and the buttons seem to work but I could not find a printed patterrn that would make the cursor do anything but barely move (The red LED does light up). I tend to like optical mice so this would be cool to have functioning.
Hi folks,
A complete IBM 1130 system just surfaced for sale in the midwestern
US. It is reputed to be one of the very first ones sold. It was used
by an architecture/engineering firm until a few years ago. It's an
impressive system: includes the CPU, external disk drives, 1403
printer, multiplex cabinet (interface for the disks and printer),
1442 card/read punch, 029 keypunch, documents and other stuff. We're
working getting more details. Buyer will have to arrange for pickup,
which will be a bit of a job as the machine is in a basement, and the
pieces weigh around 800 lbs each. (The multiplex box could weigh over
1000 lbs). We suspect that a stair crawler might be required.
We (we being Norm and Brian at ibm1130.org) don't know what the
seller expects to get for it. He's under pressure to get it sold and
moved within two weeks. This is a terrific system, but the pool of
interested people is fairly small, and the moving costs are going to
be considerable. (We would guess that the stair crawler alone will
cost $1500 or more to rent for the day, and trucking will cost
another $500 to 3500 depending on where in the US it goes -- overseas
would be much more). He's aware of this, and we hope that he's
realistic about it. We have an idea of what "realistic" might be and
could suggest what you might want to offer, if you want the advice.
If you're interested, contact Norm "at" ibm1130.org or contact me
directly, and we'll put you in touch with the seller. We'd really
like to see this system stay together and go to a person who's
interested in keeping it intact! We'd much rather see it go as a
whole package to a classiccmper than get pieced out on ebay.
Regards
Brian Knittel and Norm Aleks
Referring to people's "collections" or whatever they
may be of course. In particular I'd like to see Tony
Duell's list of, what was it, 170+ machines?? This
isn't the sort of site where a database can be stored
unfortunately. I hope I'm not being too bold...

Not yellow, but as you are in the states, try here:

I have a source in the UK for yellow ONE inch tape, and they
can make 11/16 to order, but minimum batch is hundreds if not
thousands of rolls.

It is MUCH worse for Burroughs and Univac. IBM was sold in such high numbers
that the probability of some surviving was higher. Both Burroughs and Univac
had an active "scorched earth" policies for systems in the field to keep
them out of the hands of resellers. I don't know of any Burroughs 5xxx/6xxx
systems or Univac 1100's that still exist.
John's Univac III is about the biggest old Univac system that I know of.
There is also a disproportionate number of large scientific computers that
have survived vs business systems. There much fewer in CHM's collection.
I managed to hack a Western Digital Ethernet card onto my PCjr and I'm pretty
happy about it. Using a packet driver and my own UDP implementation I can get
24KB/sec off of the machine with UDP checksums, and about 39KB/sec with UDP
checksums turned off.
The bad news is that I have a few more of these cards but the twisted pair
connector is designed for LattisNet. LattisNet is a precursor to the standard
Ethernet over twisted pair and it is supposed to be close, but my hubs aren't
buying it.
The cards have AUI adapters and I was lucky enough to have exactly 1 CentreCom
210 which works fine. I need more though - like about 10. They're on eBay,
but buying them onesy-twosy will bankrupt me on shipping.
Does anybody have a few they want to unload, or know of a good seller? Also,
are all AUI/TP tranceivers equal or should I be looking for something better?
Thanks,
Mike
