Epson HX-20 Figure, Expansion, HX-20Expansion

Expansion

Several options may be easily installed to expand the HX-20’s capability, as shown in Figure 9-2. An expansion unit provides an additional 32K of memory, which includes 16K of RAM. In addition, an 8K application ROM may be installed internally. An option ROM or microcassette cartridge may be installed in place of the dummy cartridge.

Connectors located at the back of the HX-20 enable it to be connected to a printer with a serial interface, a computer, or a modem; and to a floppy disk unit and display controller via a serial bus. A bar code reader and external cassette recorder may be plugged into connectors located on the right side of the HX-20.
