The Epson QX-10 is a microcomputer running CP/M or TPM-III (CP/M-80 compatible) which was introduced in 1983. It was based on a Zilog Z80 microprocessor, running at 4 MHz. The QX-10 provided up to 256K of RAM organized in four switchable banks, and included a separate graphics processor chip (µPD7220) manufactured by NEC to provide advanced graphics capabilities. In the USA, two versions were launched; a basic CP/M configuration with 64 K RAM and the HASCI configuration with 256 K RAM and the special HASCI keyboard to be used with the bundled application suite, called Valdocs. The European and Japanese versions were like the CP/M configurations. TPM-III was used for Valdocs and some copy protected programs like Logo Professor.

The machine had internal extension slots, which could be used for extra serial ports, network cards or third party extensions like an Intel 8088 processor, adding MS-DOS compatibility.

Rising Star Industries was the primary American software vendor for the HASCI QX series. Their product line included the TPM-II and III operating system, Valdocs, a robust Basic language implementation, a graphics API library used by a variety of products which initially supported line drawing and fill functions and was later extended to support the QX-16 color boards, Z80 assembler, and low level Zapple machine code monitor which could be invoked from dip switch setting on the rear of the machine.

Chocky's Challenge (1986)
The Q-10 is used as a front-end processor for the computer controlling a radio telescope.

Pirates of Silicon Valley (1999)
Apple acquire an NEC machine (in fact a QX-10) from Japan to get their first look at Windows.
Obviously, the QX-10 was not made by NEC, but also it was not capable of running Windows.

Our system is complete with the original keyboard, Monitor, Software and Manuals and was very kindly donated by Martin Cahn.

The FinalWord word processor from Mark of the Unicorn, which became Borland's Sprint, featured a markup language which resembled a simplified version of Scribe.
