To my knowledge, there is only one person that claims to

have a cartridge for the APL on the VideoBrain. He considers it

more valuable than gold and won't let anyone look at it or

dump its contents.

Such code running on a VideoBrain would surely warrant the /S

label for "Small".

Without some form of bank switching the resources of the VideoBrain

are minimal.

It has almost no RAM and the decoding has mirrored images through

the address space.

The F8 was clearly intended as an embedded controller similar to

the Rockwell PPS4.

The VideoBrain home computer had something called APL/S, but I can't
find any information on how it differs from APL. Does anyone know?
