I can tell you about the MOS Technology paper tape format, as used
by the KIM-1 and some other 6502-based machines. It's also a format
that some EPROM programmers accept, but unlike Motorola S-Records,
it's limited to a 16-bit address space.

This format is used by the Compukit UK101's Extended Monitor. The UK101
documentation calls it "checksum format".
