Epson PX-8 Geneva



The Epson PX-8 aka Geneva was a small laptop manufactured by Epson Corporation in the mid-1980s. It had a Z80-compatible microprocessor, and ran a customized version of the CP / M-80 operating system as well as various applications to from a pair of ROM cartridge slots that were treated as drives. For file storage, there was a built-in microcassette reader. The PX-8 did not have an internal disk drive and allowed partitioning of memory into application memory and a RAM disk, or an external 60-KB or 120-KB intelligent RAM disk module (64 KB and 128 KB). kb). used for the processor). The intelligent RAM disk module had its own Z80 processor with a battery backup. The PX-8 had an 80-column by 8-line LCD, which was monochromatic and non-backlit. It used an internal nickel-cadmium battery and had a battery life of about 6 to 8 hours when using a word processor. An extra battery provided a backup for the internal RAM. There were a number of exclusive accessories available, including a portable printer, barcode reader, and an early 3.5-inch floppy drive, the PF-10. The HX-20’s disk drives could also be used. For ROM cartridge slots, a number of applications were available: Basic, CP / M, Portable WordStar, CalcStar, Scheduler, dBase II, and Portable Cardbox-Plus. The PX-8 was not initially commercially successful, especially compared to the TRS-80 Model 100 laptop, but was growing in popularity after many of them were sold at a discount to United States via the DAK catalog. The PX-8 combined some of the features of its predecessors, the HX-20 being portable, battery powered and the QX-10 being CP / M compatible. In 1985, Epson introduced the PX-4, combining features with both the PX-8 and the HX-20.

BYTE in February 1985 called the PX-8 “a good second computer, especially for people with CP / M systems” or WordStar users. The magazine approved its documentation and tape storage, and described the display as “acceptable” but less readable than the 100 model. BYTE concluded that “after the disappointment of the Epson HX-20, the Geneva PX- 8 represents a giant improvement: it is, at the moment, the most powerful 8-bit portable available “.
