Toshiba also has files listing specs of older machines, and a file that
lists prices of discontinued items. See:
http://www.csd.toshiba.com/tais/csd/support/files/product.htm
P.S., the other page wasn't 100% complete (had the T5200 but not the
T5100) but still was pretty good. This one looks to have most (older)
models.

[Autocad not requiring math coprocessor]
Well, version 12 for Dos, which is what I have, seems to require it.
It refuses to start up, quitting with "80x87 required, but not
present". Whoever said it doesn't, maybe you have a lower version.
If so, which and what's it like? I would certainly be interested in
an older version, such a 7 or 8.

Except, that people may feel it's easier (and/or safer) to just destroy the
machine than it is to try and make sure no one can read their data. What
if some one told you, "yeah, I had one of those imsai computers, but I had
it smashed up to make sure no one could get at my old tax returns." Not a
pleasant thought.
I agree that people should be responsible for their own data, but I also
feel that we, as collectors, need to hold ourselves to a higher standard,
so that people will feel comfortable giving us their old machines.
Similarly, would you tell your analyst/doctor/lawyer as much as you do, if
you thought they might be telling everyone in the pub what you told them?

It's your responsibility to post it on the internet! 8^)
Camcorders are reasonably well understood items; what if it were a digital
camera? Someone might decide not to pass it on if they thought they might
not have erased everything...
Most of the people here probably know how to wipe a hard drive so it can't
be read. (My best guess is a low-level format, then fill it with worthless
data? Good thing I have nothing to hide!) But the average AOL user
doesn't. When Grandpa passes on, you don't want the grandkids trashing all
his old computers because they don't know how to make sure that no one will
know about all the porno sites he visited on the web.

I tried to get pics of each side and any important features... You think
even more pics would be appropriate? Or do you mean pics of more computers?
P.S., for them what was interested, I'm still working (in my Copious Spare
Time) on documenting the programs I use to generate the pages. I'll post
when I get them finished and uploaded.

<It's a Netronix 8085 SBC from around 1979 (I thought the 8085 came out a

The 8085 is late '77 I built my Netronics8085 in mid '78. I used to
call on netronics. Mine is still in use as a Eprom programmer.
The system was motherboard based with bus expansion as S100. The CPU
was a 3mhz 8085. There was also a simple serial IO (bitbash) and casette
interface on the board along with an assortment of parallel IO. The base
board could be configured to take up to 8k of 2716 eprom (or 2116 2kx8
ram) and 4k of 2114 ram. The Northstar disk and PT-VDM1 worked very well
with it makes in very compact s100 system.

No one that I know of. In fact, I question that such a device is even
economically possible to the point that a company would want to try. The
architecture differences between PCI and ISA are enormous.
The only thing I can think of that -might- stand a chance of working is to
construct some sort of sub-board that the ISA card would plug into. Said
sub-board would contain the necessary circuitry to implement an ISA-to-PCI
bridge.
This means, at bare minimum, dealing with a 220-lead surface-mount PQFP
chip and its supporting components. That means lots of skill in engineering
such bridges, to say nothing of having access to schematic capture and PC
board layout tools that can handle advanced boards...
Well, you get the idea. I'm not going to say "it can't be done" because I
think it can. It's just that I have neither the skill nor the desire to
attempt it. ;-)

Seriously look for a Weitek Math Co processor, especially if you've got lots
of RAM. They were 387-compatible FPU's that used some RAM to boost speed
dramatically. As a matter of fact, a Weitek might even be faster than a FPU
found on a Pentium or higher machine.

Having recently discovered this list, I might have a chance at getting some
help for a long obsolete Radius product: the Radius Full Page Display for
the Mac SE. My late mother bought this a while back, attached to a Mac,
for her word processing/typesetting business. It has never worked, due to
the fact that the previous owner of the Mac SE formatted the hard disk
before handing it over to her. The drivers for the card _were_ on there,
but she used the machine for weeks before asking her sons why the big screen
initialized but never worked.
The external monitor comes up, displays a half-tone pattern, then goes
dark. I did manage to get _a_ driver for the card when Radius still had
it on their ftp site, but, alas, the ROMs are too old to work with that
version of the driver. At the time, my mother didn't want to spend $80
to get newer ROMs from Radius, and now, they aren't available.
So... what I could use is either a) an old version of the FPD SE disks
(c. 1987-1989) or b) FPD SE ROMs newer than version 4.1 (the ones that
are installed there now). Besides the version number, the ROMs have a
U number (U19 and U20) and a part number (297-132-D and 297-131-D) and
a size (256K). The date on the ROM labels is 1989. The date on the PCB
silkscreen is 1987.
Thanks for any help.

P.S. - I can burn my own ROMs from images. They're just plain-old 27C256's.
I have one here that I'd gladly part with. In the original
box, with the original documentation and cassettes. The
original box, it should be noted, has been written all over and
used to mail the thing hither and yon, so it's not "pristine"
to say the least.
I don't want a lot of money for it, but I'll accept little offers
to cover the hassle of mailing it, plus postage.
The only reason I'm getting rid of it is because I'm frankly
not that interested in RadioShack stuff :) So hopefully it will
end up in a nice happy friendly collector's home being tinkered
with instaed of sitting on my shelf collecting dust.
