> Compatibility with the IBM/1400 Series has, of course, been a key factor in the success of the Series 200. The principal software components in Honeywell's "Liberator" approach are the Easytran translators, which convert Autocoder source programs written for the IBM machines into Easycoder source programs which can be assembled and run on Series 200/2000 systems, usually with little or no need for manual alterations. The Easytran routines have effectively overcome the minor differences between the instruction sets and assembly languages of the two systems in literally hundreds of installations.

It appears that Honeywell Liberator was a program to convert 1401 assembly to Easycoder, the Honeywell 200 assembly format.
