The MPF-1, or "Micro-professor" was introduced in 1981 for educational purposes by
MultiTech Industrial Corp. This later became Acer. The current owner is Flite Electronics International.
They contacted me and gracefully allowed making the materials available here, so I have no problem with
replicating their statement here:
"Published by the kind permission of the intellectual property right owners Flite Electronics International".
There are several computers having "MPF-1" in the name:
|Board in book-type package||This is my MPF-1 in its package. There are some enhancements visible:
|Speech Module SSB-MPF||The speech synthesis module is based on the Texas Instruments TMS5200NL chip.|
|Video-MPF-1||There are at least two versions of this board; the original with the
EPROM at 0800h-0FFFh and RAM at 3000h-37FFh, and a newer version with EPROM
at A000h-A7FFh and RAM at 4000h-47FFh. For the original version the monitor
ROM on the MPF-1 was exchanged by a combined monitor (0000-07FFh) /
VIDMON ROM (0800-0FFFh). But
the later MPF-1B had a monitor / Tiny-Basic ROM. So the VIDMON ROM was
relocated to A000h-A7FFh.
Useful routines for version 2.0:
The character set image is the result of the key sequence: [ADDR], A, 0, 0, 7, [GO], [ADDR], A, 0, 1, 6, [GO].
The 2.0 ROM has a deliberate routine to replace every printed [`afg by afhi^. Why is a mystery to me.
The manual for version 1.0 is at the Virtual library. A modified ROM is also available here fixing the character mangling.
