Manual for PX-8

The EPSON PX-8 is a general-purpose portable computer driven by an incorporated rechargeable battery. Standard features include a micro cassette drive, ROM capsule and RS-232C interface allowing the machine to independently handle a variety of applications. The system can also be expanded by connecting peripheral equipment such as a printer. Long time steady operation has been realized by employing the battery-powered supply system with its large capacity of 1100 mAH. A recharge control circuit to protect the battery from over-charge and an auxiliary battery (90 mAH) for backup have been added to enhance reliability.
