I just called a local (Fort Worth, Texas) University, asking about surplus
property, and they said that all Texas Universities are required to turn
their old computers over to the Texas Criminal Justice (or something like
that) Department. Has anyone else heard of anything like this, or know why
they have to do this? Does anyone in the Dallas/Fort Worth area know of any
Universities that sell surplus property to the public?
Thanks,

I was aware that Toshiba was building facsimile machines in 1928
in Japan, but I didn't know the ability to send an image to a remote
location predated the deployment of electricity.

Hi:
I'm not particularly good at C, so I'm trying to learn more as I add
tape image support to Claus Guiloi's Altair Emulator.
Anyway, I have a "C pointers" question regarding copying the tape
bits to the emulator memory. Here's some pseudo code...
//delcared in i8080.c MEMSIZE is virtual memory size in bytes
uchar Mem [MEMSIZE];
BOOL ReadTape (PSTR pstrFileName)
PSTR pstrBuffer ; //buffer for fread command
// make sure the file exists
//allocate memory to fit tape image length and load file
//determine file type (BIN or HEX)
//if BIN, make sure that the image fits into the emulator memory size
if (iLength > MEMSIZE){
OkMessage (hWnd, "Program too big to fit in memory!", szTitleName) ;
return FALSE;
}
// for binary, so get load address from user and copy to memory array
addr=MsgBox("Enter load address"); //obviously wrong. but it's only pseudo
code
// make sure that (load address + file size) <=65535
// copy binary image to the emulator memory
for (i = 0; i <= iLength; i++)
Mem[i+addr] = (uchar) *pstrBuffer+i;
return 0;
This is the important code. The Altair's memory is represented by an array
of type uchar and pstrBuffer is the file buffer used int he fread command.
My question is whether I'm doing the assignment right?
Thanks again for the help.

Ok, at least three people have questioned my remark,
so I'd like to restate it. I was going to let it pass,
but here goes.
An article in an old issue of Radio Electronics,
which was a construction article using surplus
equipment, made the remark that fax'es weren't
a new invention (new meaning 50's-60's) but that
Toshiba had built and sold them in Japan since
1928.
I posted this remark as a reply to someone who
said that the facsimile machine had been invented
in the 1700s. I found this difficult to believe
as I would have thought that an electrical infrastructure
would have been a necessary requirement.
I was corrected on this.
For anyone who misread my message and got instead that
I thought electricity had been deployed after 1928
needs to go back to school and learn English all over
again.
Of course, if we were talking about Arkansas, I
do believe the fax machine is older than Arkansas
having electricty.
Any Black Oak fans out there? :-)

The software on Apple's FTP site is all in Mac format (.HQX or MacBin).
Modern Macs have a hard time creating GCR 800K disks (if they can at all).
Apple has gone to the cheaper MFM-only drives which handle the 1.44MB disks
well.
GS/OS v6 (the latest) needs more memory than just the 1MB Apple memory
card. If your IIgs only has about 1MB then do not bother with GS/OS. The
previous owner may have been using them as IIe's (ProDOS 8) as I do with my
IIgs.
I can copy the disks for you, but you will have to send me a box of DS/DD
disks as I do not wish to lose any of my little hoard.

I *think* that ASFS v2 can only run on System 6 while ASFS v3 can run on
System 7. Both may take over the entire machine so using the Mac normally
may be impossible. Make a backup before experimenting!
My answer to the Apple II/Macintosh/MS-DOS data transfer problem is a
Macintosh LC II with an Apple IIe card running System 7.1 and the extension
that lets me read and write Apple II and MS-DOS disks. The extension
cannot handle Win9x long file names but I do no need that.

Granted, this is correct on both counts: the ps needs tested before it's
applied to the system, and the heads probably need to be parked before the
system is moved. If I understand Mr. Davis correctly, he's suggesting that
the ps be tested and possibly repaired or replaced, then the system should be
booted and the heads parked, all before taking the system home.
Try doing this in a surplus store. Hmm, and what happens if the ps is okay
but the system won't come up? Still can't move it until you park those heads
. . .
Personally, I just throw caution to the winds, handle the item as carefully
as possible (it's probably been kicked around for years) and take it home so
I can try to figure out what it is that I'm now the Proud Owner of ;>)

I have a mac plus in my collection that has something called a Hyperdrive installed in it. It's a controller card and MFM hard drive that fits behind the crt and everything actually just fits. Mine amazingly still works. Unless it was a special configuration, there was no such thing as a dual floppy SE with a hard drive.

twelve times before I could doodle. Thank god for that external 400k drive,
who would need more space?

Hello,
A friend of mine picked up a nice sony 17" (Mac) monitor, and it has the old
style DB15 connector. He wants to use it as a VGA monitor on his PC and I
don't know offhand what the pinouts are, on either end. I can make a quick
adapter to see if it works okay or not for him.
Kind regards

For anyone local (or who can get here relatively easily) and would be
interested in this ....
I stopped by the Goodwill Computer Store over the weekend, and saw that
they have a bunch (maybe two dozen) SPARCstation IPC's and IPX's, for
which they are asking $25.00/each. The people in the store didn't know
anything about their configurations (as they said, "We're pretty clueless
about those boxes"....), so I don't know if they come with any memory or
disk, and I didn't bother trying to open any of them up. Some appear
to have graphics accelerators, though (based on looking at occupied Sbus
slots on the back of the machine). There are also a couple of
SPARCstation 1+ and SPARCstation 2 machines, in about the same price
range, plus a about half a dozen HP/Apollo Series 700 machines for which
they are asking $37.50. None of these machines appear to include any
keyboards or mice. There are a few Sun monitors on the shelf, but they
are being sold separately.
To the best of my knowledge, the store does not ship, so you'd have to
physically visit there to make a purchase. I don't know who you'd talk to
there if you wanted to work out a "special deal" of some kind (e.g.,
purchasing several machines at once, for a lower price), since the
day-to-day store staff do not have the authority to renegotiate prices.

Think of Volta and his electric piles. Electricity generated by moving
wires past magnets was a later development, but there was battery power
in the 18th C.
ISTR the device required an engraved copper plate for sending and synchronized
pendula, one on each end of the transmission. I think the receiving paper was
treated in some way to change color when exposed to an electric current. It
wasn't very efficient, but to be able to transmit an image over a distance at
all was quite a feat for its day. The practical application had to wait until
the development of a national communications infrastructure.
One of my favorite quotes from the telecommunications industry was a fellow
who was chided for his enthusiasm about the new telephones. After all, we
had the telegraph - who really needs to speak person-to-person all that
badly. His (paraphrased) response: "The telephone is a wonderful device. I
think at some point, every city will have one."
