There are companies that make them *new*. They're used in some
applications where radioactivity is a concern. I remember seeing an
invoice for one (went in some medical equipment) that priced them
at $170.

Hi all,
I acquired a small lot of Alpha 166 and 233MHz CPUs. Unfortunately, the
AXPpci 33 motherboard I have does not work with the Alpha 21164-AA CPU I
found in the box of Alpha CPUs sent to me.
Does anyone know which DEC motherboards work with the Digital Alpha 233MHz
21164-AA CPU? I tried looking for information on the net, but found very
few pointers.

www.freetradezone.com has some information
but it seems to start at section 4 of the
manual and the instruction set is in
section 3.

No, we know about PAL, we just choose not to use it....

Within another ten years, surplus stereolithography machines (and other
"Santa Claus" machines) will be available to us. Good ones go for $250k,
but a friend of mine and I thought we could engineer one to sell for about
$25k, and others are likely having the same idea...
For those you you who aren't familiar with these, think of them as
"3d plotters". Some carve away at a block of material until the object
of desire remains; others deposit tiny beads of metal that are sintered
(?) together; my favorite uses a polymer fluid and a UV laser; the laser
draws a cross-section on the fluid, which hardens the polymer; a tray
under the first cross-section lowers slightly, the laser draws the next
cross-section, and so on, until you have The Object. I think another
spews plastic beads in a fashion similar to the sintered metal.
Anyone have any hands-on experience with them? I could watch, but they
wouldn't let me touch... ;-)

I used to use these at a former orkplace... a cow-orker ended up with
a few, and is down to the last one, which he's kindly holding for me...

I own a Televideo 803 system (not a portable). I have the complete system
with manuals, power cords, software, etc - even one OLD game called "mortar".
I bought the system when it was new back in the early 1980's. Still runs
like it always did - I have it in an air conditioned storage unit.

Over at http://208.190.133.201/decimages/moremanuals.htm
you will eventually find about six or so of the
VAX-11/780 related technical manuals. (They have
them already, you just need to wait until
they get around to putting them online).

I've got an old genuine IBM AT (8 MHz) that has a couple of 16bit mystery
boards in it...
1) Marked 55x3543, google says 0.5 to 3 MB board. It has a 16450 on it, a
total of 12 30 pin simms, a male DB9 (okay, I guess it's a DE9) and a
female DB25. I assumed it was a serial port and parallel port but it
doesn't show up as such in the machine. Also since these appear to be 256K
simms I expected the machine to boot with 2MB of RAM or more but it only
came up as 1 MB. I'm suspecting it's configured wrong or there's a
conflict but of course I don't have any docs... anyone?
2) Another memory board, 18 256Kbit chips, marked EV159 and has a big
EVEREX chip on it. Google says 3 MB expansion board, same questions. I
assume this motherboard has 512K on it, so... this board might be okay but
I'd like to know what the switch settings are in case I decide to add
memory to it (anyone know a cheap source of 41256s?
Any help (docs especially) would be appreciated....

Sorry about this, list, but I've just moved out to my retirement home and
I really need every cent I can gather, so I sold a Borsky S1000 handbook
and a PDP8 maintenance manual without offering it to the list. Once I
get some of my multitude of boxes unpacked, I will be offering many other
duplicates and non-essential things. I'm sure there is much that would not
excite much interest on EPay but would be of interest to the list. I'll keep
you posted.
ciao Lawrence
