I'm guessing the Videobrain APL/S was a port of EMPL, a tiny APL for the 8080 by Eric Mueller written in 1977 https://archive.org/details/ddj-1997-04-EMPL-Micro-APL-8080 that fitted in < 6Kb (and thanks to Dwight for disassembling the original code for this, given his extremely modest comment above.) Regarding porting 8080 code to the F8, this was mentioned by Jerry Fox in his article 'Tiny BASIC for the F8' from DDJ Vol 4 #39 October 1979 http://6502.org/documents/publications/dr_dobbs_journal/ where he said "Herewith is documentation and the source for a tiny BASIC Interpreter written for the F8 microcomputer. The structure of the program is copied from Palo Alto tiny BASIC written by Dr. Li-Chen Wang. It is to Dr. Wang’s credit that he wrote such an elegant program that it was fairly easy to convert to F8 from 8080 assembly language." Steve.
