Whle I have a DTR 1 and an Atari Portfolio, as well as a miserably dissappointing Casopedia E-11 and an HP 95, albeit wthout the serial connector cable, as well as a raft of Laptops, the only one that seemed to serve my needs was the Sharp PC 3000. Unfortunately mine isn't isn't working properly. As well it requires proprietary parallel and serial cables. The PC card disk one and 2 on mine also don't seem to work.
I would jump on any handheld which was as capable as it was supposed to be. Especially if it also had internet capabilites of some sort and decent expandable memory.
Has there ever been such a beast ? No CE B-Sxxt. Just Dos. A battery whch last more than 2 days ? Sound and Music capabilites. Perhaps a PCMCIA port which will take modern Specs.
And of course the same size and weight, more-or-less. Is there such a beast ?
