Operating systemsEdit

48 Sinclair BASIC, 128 Sinclair BASIC, TR-DOS, CP/M, iS-DOS, TASiS, DNA OS, Mr Gluk Reset Service.

HistoryEdit

ATM was developed on basis of the famous Pentagon (computer).

ATM was produced until 1994 by ATM and MicroArt, then the firms separated and soon closed the production.

In 2004 NedoPC (Moscow) continued the production.[8]

EmulatorEdit

Unreal Speccy v0.27 and higher.
