====PALASM====
The [[PALASM]] (from "PAL assembler") language was developed by [[John Birkner]] in the early 1980s and the PALASM compiler was written by MMI in FORTRAN IV on an IBM 370/168. MMI made the source code available to users at no cost. By 1983, MMI customers ran versions on the [[Digital Equipment Corporation|DEC]] [[PDP-11]], [[Data General Nova|Data General NOVA]], [[Hewlett-Packard]] [[HP 2100]], [[MDS800]] and others.

It was used to express Boolean equations for the output pins in a text file, which was then converted to the 'fuse map' file for the programming system using a vendor-supplied program; later the option of translation from schematics became common, and later still, 'fuse maps' could be 'synthesized' from an [[hardware description language|HDL]] (hardware description language) such as [[Verilog]].
