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.

See http://www.mikroe.com/ for further information. - STATUS: Basic OS test configuration is in place, but the board does not boot. - It looks like I will need an ICD3 in order to debug the code (PICkit3 - doesn't work for debug with this board). This effort is temporarily stalled. - configs/pjrc-8051 8051 Microcontroller. This port uses the PJRC 87C52 development system and the SDCC toolchain. This port is not quite ready for prime time. configs/qemu-i486 - Port of NuttX to QEMU in i486 mode. This port will also run on real i486 hardwared (Google the Bifferboard). |
