Great find, it looks kinda silly now. But back then, they must've sold more than one.
While he's leaning forward peering at the tiny screen he's ideally placed to take a sip of that drink through the straw
Not much later there was the Radio Shack Model 100, and a bit after that the Gateway portables, and of course, eventually the NEC Ultralite and eventually the Sharp PC-6220 (which was available under two other brands as well).
Also, for those with deep pockets there were the GRiD laptops....
None of those are 6502-based, though. I think that's why OP referenced the SX-64.
Correct. I didn't mean to give the impression that CPU was common amongst them, rather just quickly sketching out form-factor evolution.
EDIT: mentioning the Apple IIc (and later IIgs) as was done else-thread would've been more on-topic.
It weighed 23 pounds. It was approximately as portable as a tower PC. You could schlep one around, but it'd get heavy after a while.
Beat the heck out of dragging a 1702, a 1541 and a C64 around, though. I have three and they made regular trips to vintage fests because they were easy to set up. They can easily be connected to more drives or a bigger screen. Their only major drawback, and this is a big one, is that you can fry the SID if you plug in the external monitor with the power on. I did that once to my horror, and so have others.
I've only seen one in person and it was at one of the first The Gathering demo parties back in the 90's...
My father was very much the embodiment of the late 80s businessman. In the 90s he gave me his (now outdated) Dolch lunchbox. I lugged it around alright. It ran DOS and iirc was a 286 processor.
