Manny Lemas programmed the DeMon monitor (and possibly also application software) for the JOLT - the first independent 6502-based kit computer. Was a founder with Ray Holt of the company which made it. Not sure if Ray was a programmer or not. Both of them were speakers at VCF 2.0 in 1998 http://www.classiccmp.org/pipermail/cctalk/1998-August/159618.html Manny also wrote the monitor for the SYM-1. http://www.old-computers.com/museum/doc.asp?c=875
