- Actually, *none* of the "commercial" systems used it. Only the
- "homebrew and "kit" systems, and some S100 bus systems.

- It loaded BASIC files (in tokenized or ASCII format), data files
- (basicly ASCII), and "machine language" files (basicly Z80 executables,
- stored as 8-bit data with loader headers, so different "blocks" loaded
- at different addresses, and the final(?) block told the system where to
- start executing)
