[comp.misc] Motorola S19 Format

wfp5p@euclid.acc.Virginia.EDU (William F. Pemberton) (03/20/89)

I am looking for a program to convert from Motorola S19 Hex format to Intel
Hex format.

Instead of a conversion utility, I could also use an assembler for the 
68HC11 that would produce Intel Hex directly.

I would perfer either source code or something that is executable on a MS-DOS
machine.

Thanks in advance,
