Ryan to John Dobbs of Analogic Corporation. Analogic was interested in making their array processors easy to program. The [[wikipedia:array processor|array processor]]s were typically attached to a [[wikipedia:Digital Equipment Corporation|Digital Equipment Corporation]] [[wikipedia:VAX|VAX]] and were programmed in [[wikipedia:Fortran|Fortran]] using a large library of subroutines which loaded and then executed microcode into the Analogic array processor. Friedman and Ryan introduced Dobbs to APL and suggested that it would be a much easier vehicle for programming the array processors. The project was named in honour of a paper by [[Phil Abrams]]. | ||

The APL Machine evolved as an Analogic AP-500 array processor, in which the [[primitive]]s existed as microcode, driven by a [[wikipedia:Motorola 68000|Motorola 68000]]-based computing system which ran the interpreter and managed the [[wikipedia:I/O|I/O]]. | ||
