The Epson PX-8 was a small laptop computer released in 1984. It was also known as Geneva. It was moderately successful after price drops in the USA, and competed against the likes of the TRS-80 Model 100.

It had a Z-80 compatible microprocessor, and ran a customised version of the CP/M-80 operating system as well as various applications from a pair of ROM cartridge slots. For file storage, it had a micro cassette drive.

The PX-8 did not have any internal disk drive, instead allowing either memory to be partitioned into application memory and a RAM disk, or an external 64 KB or 128 KB RAM disk module to be attached (as our model has). The RAM disk module also had a backup battery for the RAM disk and an additional ROM (64 KB version only) cartridge slot.

The PX-8 had an 80 column by 8 line LCD display, which was monochromatic and non-backlit. It used an internal nickel-cadmium battery, and had a battery life in the range of 6-8 hours when using word-processing software.

Small ROM modules can be installed in the bottom of the unit which can including Wordstar, Supercalc, dBase II, and others. These ROM appear as drives to the operating system, and are accessed as such.
