OSI Challenger 1P 6502 BASIC Extensions
By Jeff Parsons
NOTE: I suspect the dump of the tape containing this machine-language program is either damaged or incomplete, which is unfortunate, because these were a nice set of Enhancements and Patches that I had created around 1980-1981 for the Microsoft BASIC Interpreter that came with the OSI Challenger 1P. Hopefully I’ll find time to dig into this again and figure what the problem is.
