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
nor any of the variety of UNIXes available for Intel machines. Nor do I
know what relation this (Rexx w/ PC-DOS 7) may bear to the REXX-88 product
that you mention - does that run on MS DOS e.g.?

According to Haddock: "Was in production by 1984, and was withdrawn on
April 2, 1986. Not many of these machines were made."
Also: "This portable had eight expansion slots and used an XT motherboard."

any machine that can run pcdos can have rexx installed as part of the dos
upgrade. according to my dos 7 manual, any machine xt and above with 512k or
greater can accomodate it.

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
module, usually you would find them being Centronics parallel or
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
transfer and are one-shot.

I remember seeing Protecto Enterprizes (and possibly COMB too) selling

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.

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.
