I am very interested in the PC work. The HP 200LX palmtop is a DOS machine with
2MB of memory and a PCMCIA port - I have a 10MB card in mine now. These devices
are still available and can be found at very reasonable prices (1MB 1000CX @
$159 -
this is a 200LX w/o built-in apps. ALL mem is free for app usage, 5 MB 1000LX
@279,
64MB 1000LX @ $835, 200LXs are a bit more than the 1000s). I have found the HP
devices to be VERY durable and reliable. They have a serial AND an IR port.
