It appears that I may have cornered, at least the local, market for
3-1/2" floppies. A recent thrift-shop find was a computer-paper sized
box (That is, the size of a box of real computer paper: wide greenbar.
Now, hopefully no one is going to ask a question like "what's
greenbar?") packed nearly full of, mostly unboxed, and used, floppies.
Nothing useful on them, just a bunch of PeeCee software for Windoze,
so I don't have to worry about overwriting anything valuable. :-)

Found a box of 53 used quarter-inch cartridge tapes hiding in my home.
These are LOW CAPACITY tapes (450 feet/137.2 meters), almost all are
3M brand DC 300XL/P tapes, some few are other brands. All are used
(contents unknown, apparently backups). Storage boxes are generally
present, in mostly good condition (some cracked), but have been written
on with marker. All have been stored inside.
You are welcome to as many as you like; tell me your shipping address
and I'll tell you shipping costs (USPS Parcel Post (calculated via
www.usps.com)). Shipping originates from zip 63132. No cost for
packing and shipping, only USPS out-of-pocket costs.
I fully expect a thundering silence; I just hate pitching them without
at least asking.

Low/no-cost preferred, but please feel free to respond if you want
money for it, or something particular in trade. I don't have a
list of what I've got handy, but who knows? I've got a pile of
uninventoried Qbus boards now and random other bits.
Thanks,

If anyone in the UK wants a MINC-11, I know where there is one, almost
certainly "free to a good home", and probably with some docs and
software. The catch is that it's in Scotland, and *must* be moved
within a week or so (owner is moving and can't take it with him).

Anybody know what this is?
It has a dial for cylinders, a disal for meas. val. (measurement value, I
presume), switches for 4 cylinders and 8 cylinders, a switch with options
"car", "ci", and "sim", a bnc connector labeled "osc. out", etc. The
display is 4 alphanumeric LEDs. On power up, it displays "Cn00" (where
'n' is all four vertical segments and the topmost horizontal segment).
I've posted pictures of the unit and some of the cards here:
<http://www.applefritter.com/temp/exiles/car/>
There isn't any brand name on it and many of the boards look custom. A
few though look like like custom prints.
I appreciate any help.

Finally found a Wang VS-85. Had to take it apart to get it in the house!
I'll be putting up some information and pictures on my web site soon.
The power supply had been removed, so I hacked together some cables and
used a power supply from something else. It has 1MB main memory, an I/O
controller for 16 serial (Wang coax-connected devices), four SMD disk
ports, a tape drive controller, and a couple of other unknown I/O
controllers.
The most interesting part:
A CE manual, describing the CPU architecture, theory, and lots of other
useful stuff, along with complete schematics for the whole system, and
most of the I/O controllers.
This machine is 32-bit, with an instruction set similar to the IBM 370.
The CPU consists of a ton of TTL chips, an ALU made of 74181's, and an
8KB writable control store. The microcode for the CPU resides on a 5
1/4" floppy disk. The floppy disk drive in the CPU cabinet can only load
microcode, you can't use it to store data.
Each I/O controller has its own CPU (or several). The old ones have a
couple of 74181's and EPROMS with a control program, the newer ones use
Z80's, and have RAM only, the control program gets loaded to them when
you IPL the system.
It's about the size of a clothes dryer. The standard power is 120vac,
but the hacked-in power supply is 220vac. Draws about 4 amps @ 220vac.

Hello,
Probably my best find at the recent Hamvention in Dayton OH was a
stack of nixie tube modules made by HP. In retrospect, I wish that
I had purchased the whole box of them, but I hopefully have enough
to at least make a clock.
I have two variations on the modules, the part numbers are:
HP 05212-6016 series 648
HP 05212-6003 series 415
They both use Borroughs B422 nixie tubes and look like they may have
an integrated HV supply of some sort.
Here are a couple of pics for reference:
http://www.ubanproductions.com/Images/nixie1.jpghttp://www.ubanproductions.com/Images/nixie2.jpg
I would appreciate if anyone can tell me what HP (or other) instruments
may have used these modules. I would also like to find a schematic of
the module if possible.
Thanks!
--tom
Thanks for that.
I tried simply zipping up a .WAV file created by the program I mentioned and
it compressed from 544kb down to 3.4kb. The original data file was 409
bytes, so although the result is 8 times bigger than the data file, storage
is not too much of a problem.
At this compression ratio (or rather expansion I suppose), a CD could store
80Mb of original computer data - more than was probably ever written for
some of those computers!.

No! Some did, many didn't.
What's worse is that some manufacturers used a constant time for each bit
(so that one state was a single cycle of 1200 Hz, the other was 2 cycles
of 2400 Hz, say), but many other manufacturers used a single cycle at
each frequency for the 2 states. This means the bit rate is not even
constant...

However, a reasonable quality digital audio recording of these old tapes
might well be enough to preserver them (you could play it back to a real
tape, or directly into the home computer). It's not an efficient way to
store the data, but it's better than losing it totally.

Strange, I'd have figured that the strong BASIC nature of the OS would
appeal to you, given some of the HP stuff you mess with. OTOH, when you
throw in the RSX and RT-11 runtimes, it does get a little unusual, but
that's part of what makes it appealing to me :^)

At least with the Mac, this isn't a good idea for long term use. It will
sometimes format the disk as DD if you tape over the HD sense hole, but
even if it does, you can pretty much count on the disk failing in a very
short period of time. I've never had a disk last more than a few
read/write sessions. After that, errors start occuring and you can't read
or write to it any more.
In many of the cases, the disk is usually hosed after this and won't take
a format back to HD anymore.
I can't say that I've really tried it outside of a Mac, so it might just
be a Mac thing that keeps it from working.
And despite the fact that some company made a hole puncher to make DD
disks into HD disks (I have one), that doesn't seem to work any better on
the Mac. In fact, in my findings, it works even worse as it rarely ever
even took the HD format in the first place, and when it did, it
immediatly starting having R/W errors and was unusable anyway.

I have six Applied Microtechnology Z80 computers, and

The BB units use the STD buss and the others have a 22/44 pin card the
same size as the STD buss card (4 1/2 by 6).
The cards are the same except the bus.
There processor, ram memory, eprom memory, DA, AD, eprom programmer cards.
I have all the manuals and softwre for them. Also 5 1/4 and 8 inch drives
and power supplies for the disk drives. CP/M comes along also.

Well, I quickly checked for Outlook. Outlook Express *could* be
different as with many other things between Outlook/Outlook Express.
To see all headers do the following in Outlook:
- open the mail message (not preview, but "full screen")
- click "View" from the menu bar
- select "Options..." from the list that appears.
The "Message Options" dialog box opens.
- In the "Message Options" dialog box at the bottom the
scroll box shows the "Internet headers:".

Being a major smart A** I can't resist pointing out the following
information in the message headers. Though since you're in a Win98 system I
suspect they're probably hidden from you (I read a lot of the messages using
'elm' on Unix so I see most of the headers). I don't think I see these when
I read the messages with Eudora on my Mac.
