Favorite portable; without a doubt - Cambridge Z88. So slick, SO portable!
Uppgradable to 512Kb internal memory, 4MB in total, Flashcards available (or build your own).
A remarkable little machine. New in stock from resellers _today_ both in the UK and US. I got mine for free from a friend who bought it at a flee market for a few bucks with 128k RAM and 32k EPROM.
Also take a look at the Amstrad NC-100, I think it's pretty similar. I also have an Osborne 1, but it's currently out of order. Working on that... Bad RAM I think
Outbound laptop/notebook: Motorola 68000 Macintosh clone. Lots of unique things about it. When it was released in 1989 it required a Macintosh SE or Plus ROM in order to fully boot. While this may have been a turn-off to some who were looking for a true Macintosh laptop it's nearly $4000 price tag made it appealing when you consider the "luggable" Macintosh Portable was nearly $7000. If you needed your donor Mac working again, simple plug a cable from your laptop into it. It also had a horizontal scroll bar as a pointing device, something I've yet to see on any other portable computer.
I liked the Panasonic Executive Partner I got at a jumble sale many years ago.
8086 based, with a half-size ISA slot. Looked like someone took a conventional clamshell laptop and expanded it 60% in every dimension.
Mine had been outfitted with a Seagate ST-251 hard drive which was weirdly glued together with a partition manager-- for some reason, writes wouldn't persist to the larger second partition. It had a gas-plasma display with two bad lines, and an interesting character ROM with italic and bold in lieu of extra colours.
I still have my "sewing machine". It started its life an 8088 with two 360 KB drives but now has a 486-66 on board. Video: MGP. Was my long time working horse when outside the house until I could obtain a laptop thanks to my employer. Yet I still use it in combination with rare hardware like a CD-shuttle: CDROM over LPT.
For me it was the chunkier but more capable TRS-80 PC-2. I think the tiny 4-color plotter was my all-time favourite peripheral.
Later I changed to the HP 200LX and despite many attempts to replace it, I just can't seem to.
If pocket computers don't count, then fond memories of dragging a Kaypro-2 to highschool on the bus and taking notes in class.
Datavue 25... First one I got to use that was actually portable.
It was definitely easier on me to borrow from my mothers office on the weekends compared to the Compaq Portables they also had. ( I weighed around 150lbs at the time)
And I had a RGB monitor for my 128, so I'd just hook it up to that for color.
I'd still like to find a working one of these, but the 3 I've stumbled across suffered horrible battery deaths.
I recently acquired an IBM P70 portable which I’m hoping to get working. Really loving the machine, keyboard and display, just gotta get it working properly. I like my Osborne 1A sewing machine too but just wish it wasn’t text only. I feel like if I can get my Franklin CX sorted out, I’ll really like that too. Recently got a Apple IIe so can finally write some disks to try the CX.
