Hi,

I picked up a couple of Epson PX-4 handheld/laptop computers a few weeks ago.
Have not got around to testing them yet. Any identifying text which used to
be on the rear labels is no longer there.

There is space for a plug-in device/cartridge on the righthand side above the
keyboard. Both computers have what appears to be a 1 megabyte static RAM
cartridge (possibly battery-backed) in this space. These must have been quite
expensive when new. I opened up one of the cartridges. Text on one of the
PCBs inside mentioned (from memory) POCKET COMPUTERS LTD 1993, so these are
quite recent.

In the EPROM sockets underneath the computer is some kind of auditing program;
the label read
    Pocket Computers Ltd
    AUDITOR V5.2
The labels also mention CP/M 2.2.

A web search for "Pocket Computers" Auditor didn't turn up anything. Does
anyone have any information on this company?
