Yes. I have a 64-256K motherboard with cassette port, too.

Nope. Except, of course, to plug in the keyboard by mistake.
A while ago, someone pointed out that IBM didn't even sell a cassette
player. You were supposed to go out to your local Radio Schlock...

Seriously, I don't see a problem, just try to keep it away from the boards,
let it dry thoroughly if you get alot of buildup, and you should be good to
go.

I just picked up a book on Macintosh Think C (MS Press, 50c, I didn't
bother getting Macsbug and others, also 50c each). For one thing, does
anyone have an extra/unvalued license copy of THINK C, version 2.1-5.0?
Also, what was the first programming language (I mean not binary or
assembly)?
Another thing: CP/M was run on just about everything, usually with
about 64K ram. How is it that MS-DOS blew up to about 384K? What
did they put in there?

I really don't have any good idea what to ask for this stuff in
terms of prices, so make me an offer. All the books are in very good
to excellent condition (no damage, no highlighting or underscoring,
etc.). I'll be accepting bids or offers until March 1, 1998.
First, I'd prefer to sell it all together, all at once, to save
myself multiple boxes for shipping. However, I'll *consider* selling
sections to people who really want it. Ideally, the person who gets
the Kaypro computers should also get the manuals to go with them.
Second, I'd prefer to sell the set to someone who can pick them up
here in Chicago, or who will pay for shipping. If you're involved with
a church or nonprofit helps organization (or a bona-fide CP/M museum),
leave me your phone number or e-mail address even if you can't afford
to buy them. If nobody is interested, I'll contact you.
Feel free to copy or repost this message in other "for-sale" areas
that would be relevant to CP/M, Z80, ZCPR, or Kaypro hardware.

Well, you could see it coming. Poor financial performance (and hence, weak
stock price) over the last few years. Weak products. Then, DEC sells-out the
Crown Jewels (its Alpha procesor) to Intel.
After listening to an interview with Eckhard Pfeiffer of Compaq, they
paid $9.6 billion for DEC's customer list, not its products. He mentions
nothing about DEC's products.
It's a shame...but it seems to me that DEC should have seen it coming.
Death comes to the last of the old-line computer companies.

That's good to know, Tony. I think I have one or two TRS-80 cables around
here somewhere. It would be nice if a Tandy cassette player would also
work; I think I have one of those here as well. I've put a couple of
feelers out there looking for an IBM variety.

Actually, I've had lots of bad luck with Compaq. They're semi-PCs (like the
Tandy 1000's) I mean, if you go to download Internet Explorer 4 from
Microsoft, they have a seperate download for Compaqs. If you call tech
support, they'll charge you for ANYTHING they can.

part of my new additions last week was a bunch of old mac stuff. i finally got
one of the 400k drives, but its having eject problems. the mechanism was stuck
so now im able to get a disk in, but when i call it to eject, the motor turns,
the disk lifts up to the slot, but wont pop out, then the mechanism goes back
down in position to read the disk. it does the same thing when i use a paper
clip; it will go up, the disk will stay in, then it goes back down into read
position. amazingly, the drive works fine otherwise. i dont quite understand
the mechanicals of it, anyone have ideas?

i enjoy reading what others have acquired, so i'd add what i just found.
apple //e and a franklin 5.25 drive $5
ibm dictionary of computer terms on disk (never opened) for $1
also, an old IBMer at work gave me some interesting things.
i got the usual 286 boards and some mfm drives and controllers.
i also got some kind of interface board that prompts for a password before
booting. made by sdi incorporated. i tried it in a 486 i built, but it wont
accept the passwoid.
also got something called a corvus systems ibm interface. it has a 34pin
header in some kind of funky mounting bracket. anyone know what it is?
also got something called a videotrax in its original but ragged box. its a
card that lets one use a vcr for backup. i think 80 meg per tape. i wont plan
to archive important data, but would be useful to image one old xt drive to
another.
i also got the host/client cards for the old pc expansion case. i have
extras, so if anyone needs them, make a deal.
i also saw a trs80 model 4? it looked like my trs80 model 3 except it had no
disk drives and was white! i never saw a white trs80. i might go back and get
it.
also found a tandy trs80 model ? which was similar in a way to the model 4
except it had a vertical 8 inch drive, but someone had gone into it and the
keyboard was missing. not bad for finishing out the week.

Atari Games is the arcade division of Atari, which is doing just fine
(though I think they're part of some MegaArcadeConglomerate these days).
The home computer and console divisions of Atari are pretty much gone.

well, you could get your 5150 in several different flavours: one, two or no
floppy drives. i actually saw a pc with no floppies, just had plastic cover
plates so your only choice of saving data would be like an early apple, just
cassette. i never knew of anyone actually doing it though. i might ask some of
the old ibmers when i go back to work.

Well, just off the top of my head, the original IBM PC came with two 5 1/4"
floppy drives. That tells me you'd have to be crazy to even attempt using
the cassette interface. Either that or have some special purpose
application (don't even want to imagine what). >>

Yes - it is an optional part of an IBM PC-DOS 7 installation. I believe
that someone mentioned that that OS will run on any Xt or better PC w/
512k memory or higher. Of course the other PC OS with great built in
support for Rexx is OS/2. I do not know about any ports to Microsoft OSes

any machine that can run pcdos can have rexx installed as part of the dos

I never saw anybody use the cassette port for practical purposes. In fact, I
never saw a cassette drive from IBM. Good trivia question. Has anybody ever
seen one? I do remember reading something years ago about hobbyists using
the cassette port for plugging in wierd hardware hacks.
The original PC came with Cassette Basic. As I recall, defaulted to that if
you had no DOS boot disk. GWBasic and BasicA had to be loaded off the DOS
disk.

The Okimate Printers employed a modular interface called a "plug-n-play

Commodore Serial (I am sure there was an Atari SIO too, but I can't be
certain...)
As far as hooking printers to the
IBM, it takes a parallel port adapter and special printer driver
software.... Given the general speed of the Commodore serial port I
would not bother. Besides, color dot matrix printers can be had for
under $50 at many thrift shops.
P.S. The Okimate is a real hog when it comes to color, expect about only
8 full color pages from a color ribbon, period. The ribbons are thermal

At a very reasonable price too I might add, I was tempted to get it
myself...

I remember seeing Protecto Enterprizes (and possibly COMB too) selling
them they referred to them as "16K color computers." This was before
Protecto started selling VIC-20s and B-128s...

Me and my friend have had a hard time with Timco. He says he will hold a
product until payment gets there, but then he ends up selling a laptop to
someone else that he was supposedly holding for me for one week. I
eventually got a refund, but my friend had the same luck with him, only he
just got a refund for the cost of the item, not shipping.
Buyer beware. Maybe we just had a run of badluck with the guy. I'm not
condemning him for two mediocre deals, just telling it how it is.

You missed my point and (obviously) poor attempt at a little humor. I'm not
connected with any authorized repair institution. I'm not sure that's what
you were implying, but it kind of sounded like that. All I was saying was
that if the mechanical parts were bent up or broke, it would be sensible to
replace it. A working 400k spare drive for a Mac would be cheap and
relatvely easy to find. Turns out it was only petrified grease. Great. Now
everybody has learned somethng.
I into classic machines as a hobby and don't try to make a living out of it.
I guess that if I did, I'd be more inclined to avoid buying parts and
repairing everything. I fix everything I can, and replace what I can't.
That's the reason that I subscribe to this list - to save a few bucks, learn
>from other people, and swap, buy, or sell hardware to and from other
collectors. I assume that's why most of us are here.
Big CHOMP!

To vent abit...
This reponses is typical of tech-support droid who do not wants
anyone to mess with internal computer parts without giving any tips
or solution besides telling them off to "authorized sites". Compaq
is pretty bad especially when I own years out of date equipment and
needs trival info on two resistors to fix a SLT power brick, I'm
still have not gotten this information yet from anything else.
Without fixing that, I can't sell the SLT 286 to others without
losing that only different type working brick cuz I have SLT 386s/20
also. @&#!
No fun to listen this especially when if that drive
is no longer in production and *is* nonstandard. All we only do want
some info and real techies are far fewer and far between common guys
with stuff that can use support help so there should not have a fear
of losing $ to those few techies. I really appreciate if some did
released this design to private makers to keep making older non
standad floppy drives for older machines.
That goes double to: any laptop drives (oh how godawful different
they're are!), Mac drives (Apple destroys their return broken parts
when traded in for credits from their authorized service support
places, thus drives up the cost becomes harder to get by the minute),
and many other different drives.
