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)
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.

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
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?
Fellow Classic Computer Enthusiasts,
I was rewatching "30 Years in the Tardis" last night and came across an item
on the tape I had forgotten about. It's been years since I watched it, and
the last time was long before I started tinkering with classic computer
emulators. Anyway, while rewatching it I was thrilled to come across a
commercial with the Doctor and Romana advertising a Prime computer. I found
some info on the net on the Prime computer line, such as:
on the net but no mention of an emulator. I also found some manuals on
BitSavers.org. Having been a Doctor Who fan for years, and with Tom Baker
being my favorite Doctor, I'd love to have the opportunity to experience a
computer system he endorsed.
Regarding my switch from an email newsletter to a weblog, there's been a
tremendous about of feedback in support of the old format. Unfortunately
the old format was just too much work for me to keep up with. I would keep
doing it if I had unlimited time and money, but obviously no one does
(except maybe Bill Gates on the money side.)
The good news: I finally got an Atom feed working. The address is
Would those of you who prefer email updates be willing to pay a modest fee?
I haven't worked out what technology I will need, but as I said before, I'd
be happy to keep doing an email feed if it were easy and not terribly
time-consuming. This isn't for profit, it's too avoid losing money when I'm
formatting newsletter emails instead of doing real work. (This also is not
any plan to contradict earlier statements about keeping the main product
free -- you have my promise on that.)
Of course, if someone points me to an automated blog-to-email conversion
technology that is SO simple and takes no time at all, then I'll just do it
without any premiums. Or maybe someone can write a cross-platform feed
reader for vintage computers. :)
I must be missing something, but I have not found a good way to
preserve a bunch of vax/vms files. I've looked at VMSZip, Gzip, VMSTar,
etc, and I must be missing something.
Here is what I am trying to do:
Before my vax finally dies, I want to take the hundred or so TK50s I
have and restore them to the hard drive and then move them to PC-land
for long term storage. This is halfway done with the tapes that are
easily readable. I now have a bunch of directories, one for each tape,
with files in them on the VAX. So the tree is only two levels deep on
the vax. The files are pretty mixed: backup files, savesets,
distributions, text files, etc. Right now the files amount to about 2Gb.
Now, the environment is: VAX 3100-30 with SCSI external. THis is where
I hooked up the TK70 (TZ30?) to read the tapes. I have network access
and can get to it via FTP and TELNET from elsewhere, namely my PC. I
also have a bunch of different SCSI tape drives, 8mm, 4mm, 9 track, etc.
So, I could transfer all the files if I could containerize (zip) them.
Do I try to Zip them somehow (what program) and FTP them, or do I just
write them to duplicate disks/tapes and throw them on a shelf, hoping I
have a machine to read them in the future?
I'm usually pretty good with this stuff, having been around the VMS
world for a few decades, but I just have this memory block, or the
blinders are on.
Certainly, there are a lot of logic analyzsers (or
analysers, if you are English) floating around. I was
told by a guy who specializes in "refurbished" (i.e.
dusted off) test equipment that this is because a lot
of it is gov't surplus where they just grab the unit.
He also mentioned that a lot of university surplus has
partially blown pods because of carelessness - due to
the nature of what they do, not much protection on the
I have a Tek 1230 which I was lucky enough to get some
pods with. I had another one w/o pods and GOOD LUCK on
getting schematics, etc on this stuff - it's a "black
art" proprietary sort of thing.
