All this noise about the younger OSes (Linux, FreeBSD)
got me thinking. I vaccilate between amused and annoyed
over the bickering between the Linux and FreeBSD contingents.
That kind of thing is part of the reason Windoze owns as
much of the matket as it does. I realize nobody could
predict the way it would take off, but when MS first started
to own the desktop, the *users* of UNIX should have started
cooperating. But instead, they went along with the vendor
factions, and Windoze won.
Yeah, I know, it was somewhat inevitable. But I don't think
it would have been quite as bad as it is. So learn from
history. Feel free to argue in private, but in public, I'd
push the overall UNIX-like OS, with just a recommendation.
Of course, it's a good feeling to even have the option.
Because 10 - 12 years ago, what were your UNIX options, if
you weren't the government or a university?
1) You could buy expensive hardware that ran a UNIX variant.
2) You bought a workstation from Sun or Apollo - still not cheap.
3) If you were lucky, you got one of the few Cromemcos or
Perkin-Elmer desktops, that ran UNIX. But they weren't
much less expensive than the Sun, Apollo, etc workstations.
(Fortune's desktops were in the workstation price range.)
4) If you were really lucky, you found a good deal on a used
PDP from someone with a UNIX license who forgot to wipe the
disks or tapes - but then you were illegal.
5) You bought Minix. Minix was cheap, and you got source, but
it was really meant to be a teaching tool. It was well done,
but extremely limited. (Nevertheless, Tanenbaum's _Operating
Systems Design and Implementation_ is still an excellent book.)
6) If you were *really* lucky, you got a good deal on a working
workstation.
Just out of curiosity, does anyone have a Perkin-Elmer desktop
running Linux? IIRC, it was pretty much a straight port of
whatever was current from bell Labs at the time - or maybe an
older version.

Well, I remember the teacher telling me that he found the computer in his
basement, and just brought it to the school to show the kids how the
computers used to be when you had to program them, and you didn't just stick
in a disk and turn it on. Apparently, I was the only one (well, there was
one other person) that was interested in it.

Hi!
Want to sell one of the Convertibles? It doesn't matter that there's no
power supply, or even if it works or not. I collect old laptops, and the
Convertible is one of the ones that I don't have.
ThAnX,

The thermal printer and RS-232 interface were both produced, but not in
large numbers. They're hard to find. A few pieces of cartidge software (or
as TI liked to call it, "Solid State Software") were produced, AFAIK, but
also not in large numbers. I've never seen any in six years of looking.
The tape drive, called a "Wafertape" drive, was pretty much vapourware.
There were a few prototype units sold, but it was never in full production,
because TI couldn't get the bugs worked out. The box for my CC-40 has a
sticker attached that says "Tape drive not available". The lack of
secondary storage pretty much doomed the CC-40 as a computer; it never
caught on.
I think there was an article in the book "The Best of 99'er Magazine" on
how to build a cable to connect a CC-40 to a TI-99/4A. I also used mine as
a programmable calculator.
Cheers.
Mark.

Well, I think the only card that was in it was the video card (HD and floppy
controllers had been removed). The first slot (closest to the side of the
case) on the XT and PC motherboards do match up. I think for the cassette
port, he just drilled a hole in the case, or cut something. I'm not too
sure how he did it, because it's been 5 years since I've seen it.

2.0 is better still and MINIX-vmd is supposed to be hot.
I finally picked up the book/cd at Boarders for $53.

Oh, so you're saying that Linux will defeat FreeBSD solely because of its
possibly superior development model. So, where does the DOS\CP/M comparison
come from?
Does anyone want/need OS2 2.00.1 ? I have quite a few sets of these I set
aside in a box many years ago.
Also, if anyone needs any of the stuff that came with the IBM Valuepoint 33Mhz
DX systems (user guides, etc) I have plenty of sets of those too. Most
of this stuff is still in shrinkwrap.

My teacher had replaced the XT motherboard with a 5150 board when the HD and
floppies quit, so that ROM BASIC could be used with the cassette port.
