I downloaded nspark.tar and compiled it for Linux. It recognized and 
extracted the archive, but the resulting file is different from the raw file 
as Johan sent to Chris. Perhaps it contains control characters meant for the 
RISC OS?

Extracted file: 4C 05 81 4C 32 80 82 1C 01 45 50 52 4F 4D
Actual file: 4C 4C 32 45 50 52 4F 4D

Anyways, it's a shame the file doesn't fit Chris' programmer, now that so 
many people tried to help. I know the feeling. I have an old IEEE-488 EPROM 
programmer meant for the Commodore PET. However I don't have a single byte 
of software or have found any traces of suitable software on the Internet. 
At the place I found it, there still are boxes and boxes of more or less 
documented floppy disks, so it is possible that one of them holds some EPROM 
software for this particular unit.

In the mean time, I bought myself a modern USB based programmer that does 
most (but not all) of the vintage EPROMs that I'd ever want to program.
