The 5140 is the IBM convertible computer released in 1986, two years after
the 5155. A real nice machine, BTW. Closer to a true portable (weighs in
at about 12 lgs.) than the previous luggables by IBM, Compaq, Kaypro, et.
al. Also one of the first (not sure of what I speak here) with a LCD screen.

I had bought an AT at an auction sale once. it was the old type 1 board, with
512k and double stacked ram chips. much to my surprise, it was upgraded to the
familiar AMI bios, which of course gave it type 47 for user defined drives!
should of kept it for that reason. i sold it before i started my collection in
1991

<< Correct. The PC/AT bios only stores a drive code (a number that points to
a table in the ROM) in the CMOS RAM/RTC chip. There's no support for
storing drive parameters there.
That's why there's a kludge ROM in this machine with a patched drive
table so I could add a larger IDE drive to it. >>
When I usta repair Xerox machines, I used trichloroethane to get rid of it.
Do NOT put trichlor on hot metal (such as a fuser), or else you'll end up
with phosgene gas, which is -- shall we say -- slightlu harmful. (It was
one of the war gasses used during WWI).
I've heard that trichlor was outlawed, but I still see it around. My
favorite all-around solvent is MEK, but I haven't tried it on toner.

You can also find System .97 and some other older systems and software to
run on them available on some page out there. Do a search on
classic+mac+software and it should pop up towards the top.

I think that's how I got subscribed to this list. I came across an obscure
reference to it on a web page and posted a message to it, pre-apologizing
for posting, and asking how to subscribe. Someone immediately helped me
out, and I'm now on the list.

Isn't complaining that something is off-topic be off-topic in itself?
Wouldn't that complaining be better directed to the list admin or to
the off-topician themselves?
That's my insight on the matter, on-topic, off-topic, under-topic, et al.

i havent had any problems finding either a 5140 or 5155. i have two portable
pcs and one convertible which i traded a nic for. i have seen 5155s at several
hamfests, and even saw two at a hock shop for $150 each <!> I have a book that
says the 5155 was "rare" but i disagree. i'd much rather love to find a
complete 3270pc or a xt370 or even an at370.

I just picked-up an IBM Portable Personal Computer (Model 5155, I believe
its basically a portable XT with dual 5.25" drives and a bulit-in monitor,
512K). [Hey Roger, it's got a handle!] I was also able to find the
Operations Guide for it at another place. Very cool.
QUESTION: Does anyone know how many of these were produced?

I would like to inquire about the printer's cable connection. Will it
accept a standard centronics cable? I would appreciate any information
that you can give me regarding this matter or any information that you may
have about the availability of an Okimate 10 module that would allow
connection with a centronics cable.
--Thank You--
