P112 CPU Board Support

Welcome to the D-X Designs' P112 CPU Board Support Site, dedicated to continuing support for the P112 CPU Board.

Some background -- Dave Brooks (the designer of the P112 CPU Board) is no longer selling this board, and the future of Dave's P112 page is uncertain at this time. Being a P112 owner myself and interested in helping continue support for the P112, Dave Brooks suggested I mirror his P112 page. I have decided to set up this website - hosted by my ISP - as a mirror of Dave's page with some modifications. I have substituted my mailing address for his as a new contact for suggestions and contributions.

(Dave's P112 page can still be found at the original P112 homepage).

The software archive is open to anyone wishing to contribute code they have written for - or ported to - the P112.

New! Contributed Dec. 2002 - UZI180 for the P112 - Hector Peraza's corrections and bug fixes of Hal Bower's UZI180.

An excerpt from Hector's documentation:

"UZI180 is a unix-like operating system for Z180-based machines. Derived from UZI (a Unix Edition 7 lookalike system for Z80 machines), UZI180 further benefits from Z180-specific features like 1Mb addressing capabilities, internal timer-counter, etc.

The orginal UZI180, as posted on the TCJ, was a snapshot version of a work in progress. As such, it was far from stable and many features did not work properly. I've done many corrections and bug fixes to the sources that increased the overall stability of the system (it used to crash quite often with a "Trap @ 0xXXXX" message)."
