Epson PX-8

The PX-8 did not have any internal disk drive, and instead allowed 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 moxel); the RAM disk module also had a backup battery for the RAM disk and an additional ROM (64 KB version

only) cartridge slot. Data can be saved onto the built-in micro cassette tape drive.

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.
