| The Epson PX-8, also known as the Geneva in the United States, is a portable CP/M-based computer released in 1984. It featured a Zilog Z80 CPU running at 2.5 MHz and came equipped with 64 KB of RAM and 32 KB of ROM. Its display was a built-in 8-line by 80-character monochrome LCD, capable of showing 480×64 pixels. Unlike many other CP/M systems, the PX-8 did not include a built-in floppy drive. Instead, it relied on external storage options such as microcassette drives and external 3.5-inch floppy drives. The operating system and key applications, including WordStar and BASIC, were stored in ROM, making the system boot quickly. The PX-8 had a full QWERTY keyboard and supported optional ROM cartridges for additional software. It was notable for its built-in rechargeable battery, which allowed for true portable use, and its compact, lightweight form factor. Expansion options included a serial port, parallel port, and a modem interface, making it suitable for mobile business use in the mid-1980s. |
