''One of the most interesting Apple ][ clones I have seen. This machine claims to be a "Multi-System" computer, and the manual speaks of future advancements, allowing other systems to be housed. Basically, it is an Apple ][ with a Z80 Card, which can boot into CP/M or Apple ][ software. Instead of saying APPLE ][ on boot, it says -:FOX:-''
Please consider donating your old computer / videogame system to Old-Computers.com or one of our partners from anywhere in the world (Europe, America, Asia, etc.).
Documentation such as manuals and schematics are now available at my blog here: https://jbretro.wordpress.com/2018/09/01/fox-640-computer/
I purchased a complete Fox 640 computer from local seller (Canberra, ACT) who kept all the original documentation, which was scanned and shared above.
