DOS Palmtop: ZEOS Pocket PC Details and specs


About this machine:

Although many people believed the ZEOS Pocket PC was a miracle handcrafted by the U.S. ZEOS company it actually just is yet another Titalwave PS-1000 OEM edition. However - at least in North America this may be one of the best known DOS based palmtops besides the HP series and the Portfolio as it was marketed and distributed quite aggressively and at the time at a quite reasonable price from a quite well known company. Like all Tidalwave PS-1000 clones it is quite big and heavy and does not have the best firmware/BIOS but at least it comes with MS Works. These at least come with a US keyboard and English software.
