> "The Flop.

MUTOS 1835 was a UNIX port which we did under contract for an AT-compatible from Robotron. Since this machine was never produced, the whole thing must be seen as a flop."

Yeah, just about 20 EC 1835s were built (the "C" is the Russian "S"; they're ESER (ES EVM) machines, after all). But then again, there's MUTOS 1700 (for A 7100 and A 7150) and MUTOS 1834 (for EC 1834)... along with CP/M, CP/M-86 and DOS, of course. The 32-bit (386) follow-up to the 1835 was planned for 1993/94. Well, history had other plans. I remember my first programming lessons in my school's computer lab in 1991... on Amstrad 386DX/20 machines.
