The URL below contains several Epson PX4 manuals. Somebody (Dave?) was
asking for technical info on that machine. There's no service manual, but
there is the Operating System Technical Reference (it's the files
starting with 'osrm'). It's really a programmer's manual, so it
doesn't
contain a full schematic, but it does contain I/O port details and
pinouts of the connectors (including the cartridge port), and examples of
how to design cartridges.

May be of interest, anyway...
