There were several models : 20, 21, 22, 23, 24, 25 and 26. The Model 2x was the successor of the ABC 10, which had a digital tape auxillary memory, supplied with DOSKET-T.

A lot of languages were developed for these computers:
- Dosket : Fortran IV, Basic, Cobol, Macro Assembler.
- CP/M : MBasic, CBasic, Pascal, Cobol 80, Fortran 80, PL/3, etc.

(AI DOSKET is the AI Electronics Operating System.)
