The Sord M-100ACE was the professional version of the M-170, offering as standard a floppy disc controller card, a single or dual 5" 143 KB floppy disc unit and a colour graphic video card.

Several I/O interfaces were also added and business oriented developpement tools could be used: FORTRAN and BASIC compilers and COBOL language.

Four successive version were sold - M100-I to M100-IV - offering various hardware and design improvements.
The model pictured here is a M100-III.
