This seems like a good place to ask this question - I'd like an Apple Lisa 1
"twiggy" system for my collection, and can trade a working IBM 5100 Portable PC.
We'd probably have to meet in person to make the transaction. I'm in So CA.
Thanks-

I think there's a rather large disparity in value between the two systems.
I'm not sure what an IBM 5100 would go for these days, but a Lisa 1 will
generally sell in the $10K+ range minimum these days.
I had two Lisa's with Twiggy drives: one I sold for $9,600, and the other
for $14,500. That was over 8 years ago.

Well, it ain't in the 5150/5160 range!
The 5100 new was $10K to $20K.
I haven't seen any available in a long time; although one sold on eBay in
June for $10K.
I had a standing offer for Jon Titor, that in exchange for a one-way ride
back 60 years, I would get him a 5100 (with BASIC and APL), AND, set up a
stock portfolio in the 1960s to fund his activities.

I had a 5100 that a dentist had bought as soon as
it came out and he
added the floppy drives and printer. It was a direct IBM buy for 31000.

Also a fair amount of software.

Are you sure about that? The 5100 doesn't support
floppy drives. And I've

$3100 is about what IBM charged for a fully loaded 5150. (PC)
THAT is not a 5100! $3100 for a 5100 would have been a bargain.
A 5150 would not be worth as much as a Lisa.
A 5100 would be. (or at least in a similar range)

The referred to guy was a dentist who had had this in a closet for 15
years or so, had written a couple of floppies worth of programs, and
otherwise had not done anything with it.
it was all in the trunk of a huge ass Cadillac convertible. I was one
of the first who came by, and bought it on the spot. Drove to my truck,
offloaded it and sent him on the way on an early Sunday morning. At the
ACP Swap Meet in Santa Ana. He wondered if he asked too much, and
wanted it gone and didn't want to really be in the middle of a spectacle
over it and how little he got out of it.
I was glad to get it.

the 5100 has an external connector. The floppy drive is a floor unit
about the size of three AT units upright, with two single density
floppies in it. We used my unit as an engineering reference to do a
floppy interface project which required 3740 compatability from our
hardware.
And there was another connector on the back of the unit to daisy chain
the printer. This is the 5100 desktop unit.
I've got 3 of the floppy drives. Ethan Dicks was kind enough to retrieve
another system for me from Pittsburgh, PA some time ago and is storing
it for me at his house. Got the printer and the floppy unit.
I've got one of the units with the integrated 8" floppies as well.
Initially a 5150 was 6000 and wasn't fully loaded. A friend against
computer advise bought one along with an IEEE interfaced 5mb drive when
the PC first came out.
thanks

Yes, three Sub-D connectors. Two for the signals, one for power.

And that floppy drive (if you are thinking of the IBM 5114) does *not*
work on the 5100. The 5100 simply has not the "driver" for it.
Is it possible that you are thinking of the IBM 5110 ?

You could only attach up to three IBM 5106 external tape drives and one
5103 printer at the end of the chain. There wasn't anything else AFAIK.
I've got one of the units with the integrated
8" floppies as well.
That is the IBM 5120 aka IBM 5110 model 3.

There is an IBM 5100 on eBay right now:
https://www.ebay.com/itm/314137209812 <https://www.ebay.com/itm/314137209812>
In 2018 I saw a BASIC model sell for $2500. I’ve seen a working APL model sell for $6150
in 2021.
I’ve been keeping track of Lisa 1 sales on eBay for some years. I take a screenshot of
the finished auction and also save all of the photos. They sell for a lot, and I wonder
if they will one day be priced like Apple 1 computers? I remember when Apple 1 computers
were going for $10K - $20K, and now they go for the price of a house.
Twiggy drives only:
Mar 14, 2017 : $32,100.52
Face plate only :
Mar 14, 2017 : $4,602
Complete Lisa 1 system:
Apr 25, 2017 : $99,500
May 11, 2017 : $55,300
Jan 14, 208 : $56,100
Mar 25, 2018 : $55,300
Nov 11, 2018 : $65,000 (did not sell, later marked as “no longer available”)
Sep 7, 2019 : $43,900
