The following information was taken from a vintage computing website. If you have read my page about the HP 200LX then there is not much to be said about the 1000CX. The internal HP codename is "Puma". The only difference to the 200LX is that it lacks ALL software on the ROM besides of course the operating system - MS-DOS. The only other difference is that the case comes in black instead of dark green.Some large companies like Coca-Cola reportedly used these together with custom warehouse management software.

Only what comes with MS-DOS!

Originally retailed for:: 450 USD (1 MB version, the 2 MB Version retailed for 499 USD on release). Clone of: Not a clone. Software-less model of the 200LX in black. Similar models: HP 95LX, 100LX, 200LX, Omnigo 700LX. PCMCIA 2.0 Type 2 slot: Can use flash cards or compact flash (With PCMCIA Adapter). Fully CGA compliant, so most CGA based DOS appz and games work. Keyboard extremely small, not comfortable for really typing a lot. Infrared not fully IrDA compatible. Among the more expensive HP models.
Really absolutely NO software on ROM. Give it a usability value of 9/10 if you love the tiny keyboard. Why this even features an own internal HP codename is hard to understand. Actually all they did was taking a HP 200LX and deleting all software.Well the ROM is now just 1 MB instead of 3 MB. If you can get this cheaper than a 100LX or 200LX and you are sure you never need any of the original ROM software then maybe worth thinking about but otherwise probably the worst choice of any HP Palmtop after the 95LX.
Although less useful to the normal user this is a bit more rare than the 100LX and 200LX versions so a tad higher collectors value. Still these are far from being "rare". The item "Vintage HP 1000CX Palmtop PC 2MB RAM" is in sale since Friday, July 5, 2019.
