I have been told by the software house who supply us at work that there
might be some old PX4s and PX8s in their storeroom which no-one wants any
more. Does anyone know what these are?
I gather that htey may be some sort of intelligent terminal as the chap
comcerned said they they used to be used on site and then plugged into a
modem to upload the data to their main database.

If they are made by Epson then they are early 8 line LCD screen laptop
machines running CP/M, at least the PX8 is, never heard of a PX4 personally.
They had a neat little thermal printer option too that anyone with the mini
din pinouts and some cable making could adapt to a nice printer for a serial
port on another machine, such as a PC (right Max?) but they'd have to use
thermal fax roll paper in it.
Help at all?

A PX4 is either an output triode (:-)) or more likely, an Epson laptop
that runs CP/M. It used EPROMs as pseudo disk drives (read-only of
course). A PX8 is similar, except that it has an 80 column display and a
built-in microcassette drive.
Not bad little machines, actually.
The PX8 (don't know about the PX4) could use an external 3.5" floppy drive
option as well as the ROM disk drives. The programs on microcassette were near
as bad as a Vic 20 on loading BASIC programs too. 80 columns yes, 24/25 lines
no. It (PX8) had a mere 8 lines, being a pain to run that flight sim in BASIC
on. I beleive that most of the bundled software existed on ROMs as well. Damark
started out pretty much in the surplus computer sales on the PX8's and a few
others around 85/86..
I think I still have a null modem cable I made up way back when to attach to
the serial port of the PX8 mini-din (printer connection essentially) to go to
my then hi-tech Sanyo pain-in-the-butt MBC-555-2. I think I should have kept
the PX8 and sold the Sanyo now that I reflect on it. ;-o
