I still think it's an MF 1.x, because I just found a foto of one without the 
extra socket (but there are holes for it). Please check if there are ICs 
under the 6821 and the RAM or EPROM. You should find another 74LS33 and a 
74LS30 and 74LS00.

The lower side should read "MF1" and "(c) 1986 by GREWE COMPUTERTECHNIK" if 
it isn't a pirated clone.
