The P112 is notable because it was the first of the hobbyist single board
|
|
computers to reach the production stage. The P112 hobbyist computers
|
|
were relatively widespread and inspired other hobbyist centered home brew
|
|
computing projects such as N8VEM home brew computing project. The P112
|
|
project still maintains many devoted enthusiasts and has an online
|
|
repository of software and other information.
|
|
|
|
The P112 computer originated as a commercial product of "D-X Designs Pty
|
|
Ltd" of Australia. They describe the computer as "The P112 is a stand-alone
|
|
8-bit CPU board. Typically running CP/M (tm) or a similar operating system,
|
|
it provides a Z80182 (Z-80 upgrade) CPU with up to 1MB of memory, serial,
|
|
parallel and diskette IO, and realtime clock, in a 3.5-inch drive form factor.
|
|
Powered solely from 5V, it draws 150mA (nominal: not including disk drives)
|
|
with a 16MHz CPU clock. Clock speeds up to 24.576MHz are possible."
|
|
|
|
The P112 board was last available new in 1996 by Dave Brooks. In late 2004
|
|
on the Usenet Newsgroup comp.os.cpm, talk about making another run of P112
|
|
boards was discussed. David Griffith decided to produce additional P112 kits
|
|
with Dave Brooks blessing and the assistance of others. In addition Terry
|
|
Gulczynski makes additional P112 derivative hobbyist home brew computers.
|
|
Hal Bower was very active in the mid 1990's on the P112 project and ported
|
|
the "Banked/Portable BIOS".
|
|
|
|
Dave Brooks was successfully funded through Kickstarter for and another
|
|
run of P112 boards in November of 2012.
