Four 65XX and one Z80 SBCs, the EMUF series of the german magazine MC Die Mikrocomputer-Zeitschrift.

The EMUF pages are a tribute to the work of the editing staff of MC Die Mikrocomputer-Zeitschrift on SBC’s.

EMUF stands for Einplatinen-Mikrocomputer für Universelle Festprogrammierung, Single-board microcomputer for universal but fixed applications.

EMUFs SBC’s are programmable systems, without a monitor program: write a program and store it in an EPROM and run the application type of system. A bit like the modern microcontrollers like the PIC and AVR IC’s and also a bit like the Arduino’s. But with the technology of the 80ties: 8 bit CPU’s like the 65XX and Z80, I/O IC and EPROM and some RAM.

The first EMUF was published in 1981 in the second edition of the magazine. Often used with just the name EMUF. It could better be called the 6504-EMUF, since the CPU is the MOS 6504, a stripped version of the 6502.
In the years 1981 – 1986 several small SBCs were presented, EMUF-232, 6502-EMUF, Z80-EMUF.

A special one is the MC-65, a AIM 65 compatible 65C02 based SBC, able to runt eh AIM 65 ROMs.
