There were several models : 20, 21, 22, 23, [24, 25 and 26](/museum/ai-electronics-abc-24/). 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.)
