Home Page Forums MAME MAME Triumph-Adler alphatronic P3 (+ P1, P2 and P4)

I got another CP/M machine from a German company: The Triumph-Adler alphatronic P3.

MAME already supports its little homecomputer brother, the alphatronic PC and its distant cousin, the ITT3030



The P series machines and the ITT3030 were designed by SKS Steinmetz, Krischke Systemtechnik GmbH who sold P2 lookalikes under the "KISS" moniker.

The very suave SKS nano 2500 in its bordeaux red leather case shares some of that DNA as well, more about that later ...
SKS Nano 2500 which would make a nice addition to MAME as well

This brochure

P2: Integrated Keyboard, 6K PROM, 1K RAM internal, 48K RAM, 2x160KB Floppy SSDD
P2 S: Integrated Keyboard, 6K PROM, 1K RAM internal, 48K RAM, 1x320KB Floppy DSDD

Alphatronic P30 and P40 were P3 and P4 which were extended by an 8088 coprocessor card and extra RAM.

They have a serial printer port via the 8085's SID/SOD pins and a universal serial interface via a 8251.
