Does anyone remember on the old Archimedes Version 4 linker (before Keil bought them out) how to link into a HEX file? Or how to convert from the old .A03 file to a HEX file. Version 5 software linked into a .ABS file and then the OH51 utility converted it to HEX. The Version 4 doesn't have a OH51 utility and the Version 5 OH51 doesn't work on Version 4 .A03 files. Though someone might remember from back then. Thanks. By the way, I can load the .A03 into a Nohau emulator and save the code to HEX once loaded, but my old emulator is getting flaky. So, I was hoping of a conversion process. Sutton
