Previous, TPG 9 link
TPG 10 is in progress and I’ll be doing youtube slop vlogs during this time too!
This will cover most IBM’s Luggable, Portable, Convertible & laptops they had released in America and European markets.
I will omit some Japanese models, specifically 5523, as they are a precursor to the 200, 300 and 500 Series machines, so that family tree will stay intact. Sorry this is just how I do because of OCD and a bit of the ’tism.
Price research done from April 23rd to 28th, 2025
1984 & 1987-89 USA Luggables
| IBM Portable PC (CRT) | MTM | -xxx | Sold | Low | Mid | High | EX+ |
| 5155 Model 68 | 5155? | 68? | 15 | 227 | 375 | 680 | 1115 |
| PC Convertibles | 12 | 180 | 300 | 436 | 650 | ||
| 5140 Model 1 | 5140 | -002 | 10 | 180 | 300 | 450 | 650 |
| 5140 Model 2 | 5140 | -022 | ? | – | – | – | – |
| 5140 Model 3 | 5140 | -003 | 2 | – | 545 | 595 | – |
- 5155 – $85 for a PSU… most of thees wil l be for parts.
- Scoop up the BIN listings, there are a few below mid price, but otherwwise they will just be auctions and don’t overpay to win a bidding war… even the high price unit has a display issue at times.
- Less of these sold since my guide last year
- PC Convertible all – Most likely will get one for parts, ones that turn on seem to go for high.
- Model 2 – Clicked on 3 listings, no seller has info stating they are Model 1 or 2, so I’m just going ot assume most are Model Ones.
- Model one has a mono panel, Model 2 is a SuperTwist panel.
- Model 3 – These two boot up and have a working backlit LCD.
- Model 2 – Clicked on 3 listings, no seller has info stating they are Model 1 or 2, so I’m just going ot assume most are Model Ones.
- Looking at the previous price guide that I did in June 24 2024
- Prices kinda went down.
- Some of the low prices are lower now, mid with the 5155 as well
- EX+ is still about the same prices
- High price went up by like 40-80 but honestly

- 5535 Any – Nothing per usual 🙁
PS/55 Desktop Clamshell
This thing is elusive, all I know is its just a big ass all in one PC, a luggable. It is in laptop form factor, but it does not have a battery as far as I can tell.

- seller adickson (30K) had 3 of them for sale (with different serials & had a item number for each!). Two were 1 bids, and a BIN, last seller (jcsjcs) was BIN and was high. wow! Hinges still sell lol.
- Arguably these were a great price vs the P70.

- PS/2 Note Any
- EX+ is a TP 700…. a few desktops & P70’s mixed in. Also there are CPU upgrade cards for about $80, though i think it has a slot for a math co-processor (or thats the CPU…).
- N51 SX
- Seems like the left hinge either breaks or the plastic breaks around it. Mid turns on to a blank screen (CGA works), and high price screen turns on. Both BIN
- N51SX SLC
- Untested, rough, BIN, damaged hinge bezel (prob the hinge fucked)
- PS/55 N51SX
- Nothing…
- CL57 SX
- AVAIL LISTINGS ARE OVERPRICED!!!! EX+ is supposedly tested and working but doesn’t show a picture of it on, do esn’t list the specs…. so scammer. Mid and high are untested.
- PS/55 N57 SX
- Nothing, Other units.
- PS/2 Note N33
- Seller linked, provided excellent & detailed photos of this rare model! The MTM is actually on the rear ports behind the door cover! I actually came across this accidentally for looking up the Japan PS/55 version of this machine!
what would I collect from here?
Considering my collection… P75 would be one that I would get, P70 if I cant find one, IDK 386 and 486 performance differences. Seriously the electroluminescent panel is fucking cool as fuck! it was only a short window that laptops or Portables were made with these. I believe the Honda S2000 had one of these panels for their instrument cluster, its fucking badass!
Yeah I’ll skip the L40SX, sorry I don’t like that thing. Instead I would get a GridPad Compass instead, they are way more cooler, and come in black!
Next would be a CL57 SX because its the first color screen IBM laptop, a precursor and fucking insane behemouth considering how small the ThinkPad 700C is.
Of course I would like to get a PS/55 machine, but not necessarily these.
