6502-EMUF
Published in MC 1982 issue 2 the 6502-EMUF is a 6502 CPU based SBC. More modern with 6522 as I/O. Alas this issue is not available to me yet, but later articles are a scan from MC 1982 issue 8, ‘RAM Erweiterung’ and a scan from Sonderheft 2 : ‘Entwicklungshile Ein monitorprogramm fur den 6502-EMUF’, as shown below.
Please if you have the MC 1982 Issue 2, help me!
I also added at the end of this page the article from MC 1985 – Issue 5 (thanks Gerold Pauler) about a EMUF6502 with more RAM and I/O.

EMUF and MC
The EMUF pages are a tribute to the work of the editing staff of teh german magazine MC Die Mikrocomputer-Zeitschrift on SBC’s.
EMUF stands for Einplatinen-Mikrocomputer für Universelle Festprogrammierung.
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.
Here you find on the following pages information on the EMUF and other SBC’s published in the magazine, Sonderheft and books:
- EMUF and MC Die Mikrocomputer-Zeitschrift
- (6504-)EMUF
- EMUF-232/V24
- 6502-EMUF
- 6809-Einplatinen-Computer
- Z80-EMUF
- Z80-Mini-EMUF

EMUF and MC Die Mikrocomputer-Zeitschrift
The EMUF pages are a tribute to the work of the editing staff of the german magazine MC Die Mikrocomputer-Zeitschrift on SBC’s.
The EMUF pages are based upon:
– the MC magazine: 1981 (1-4), 1982 (5-12, 1983 (1-12), 1984 (1-12), 1985 (1-12), 1986 (2-12).
See the links for scans. Missing are 1982 (1-4), 1986 (1) and later. please help me!
– the EMUF Sonderheft (thanks to Dick Blok) and in scanned format available from the EMUF 6502.
– the book Mit Computern Steuern partial scan, only EMUF related pages, download here
The Sonderheft 2 dedicated to the EMUF is available here.
EMUF stands for Einplatinen-Mikrocomputer für Universelle Festprogrammierung, Single-board microcomputer for universal but fixed applications.
Here you find on the following pages information on the EMUF and other SBC’s published in the magazine, Sonderheft and books:

From wikipedia.de:
Die Zeitschrift mc war ein von Januar 1981 bis mindestens Oktober 1996 monatlich erscheinendes deutschsprachiges Computermagazin.
„mc“ stand für Mikrocomputer, was sich auch im Untertitel der 1980er-Jahre Die Mikrocomputer-Zeitschrift widerspiegelte. Sie wurde von Herwig Feichtinger mitgegründet, der zunächst auch Chefredakteur war, und kostete zu dieser Zeit 6,00 bis 6,50 DM. Entstanden war die mc aus einer festen Rubrik der Funkschau. Zwischenzeitlich wurde der Untertitel geändert in Computerpraxis für den technischen Anwender, schließlich in Systemübergreifendes, technisch orientiertes Know-how. Mit der Ausgabe Juli 1994 erschien sie nur noch als Beilage zur Zeitschrift DOS International, hatte aber immer noch einen Umfang von etwa 45 Seiten. 1992 bis 1993 erschienen insgesamt fünf Sonderhefte mit dem Titel WINbox. Spezial-Magazin für Windows-Anwender.
Redakteur und später Chefredakteur der Zeitschrift mc war Ulrich Rohde, welcher 1983 auch den WDR Computerclub mitbegründete. Herausgegeben wurde die MC anfangs vom Franzis-Verlag, ab Juli 1994 in Form einer Heftbeilage vom DMV Verlag als mc extra.
Die mc befasste sich mit Computerthemen, Netzwerken, Hardware, Datenbanken sowie Programmierung. In den letzten Ausgaben gab es die Rubriken „Grundlagen“, „Programmieren“, „Technologie-Report“ und „Test“, in denen Beiträge als Einführungen bzw. Zusammenfassungen zum jeweiligen Thema im Stil wissenschaftlicher Fachblätter geschrieben wurden. Die Redaktion war mit Naturwissenschaftlern besetzt.
Eines der bekanntesten Projekte der Zeitschrift war ein auf dem Mikroprozessor 6504 basierender Einplatinencomputer namens EMUF.
