I'm trying to understand various hex formats so I can add them as output options to minipro[1]. I went looking for existing code to convert binary to Intel hex and found repeated copies and references to "format83.c" by Erik Lindberg. It seems to do what I want, but I'm unclear what "Intel HEX 83 format" is supposed to mean. Based on what I see at http://www.math.purdue.edu/~wilker/misc/DEVEL/0036/A-6804/BIN2INT.C, this program only creates hex files in the I8HEX format, as described in https://en.wikipedia.org/wiki/Intel_HEX. Of course, I'm going to have to support the I16HEX and I32HEX formats too. Based on what I find in format83.c, this shouldn't be too much trouble, but I really want to know what "Intel HEX 83" is supposed to mean.
