I have Intel HEX format files for all the H89 ROMs. This is an easy
format to burn EPROMs from; all EPROM programmers recognize it, and CP/M
has no trouble reading and writing it. The H-17 ROM (444-19) is the same
one used in the H8.

It is interesting that none of the H89 ROMs have any copyright notices
printed on them, or hidden in the code inside. Heath also widely
distributed the source code for them in printed form (the source code
*did* usually have copyright notices). My assumption is that Heath was
very open to distribution of the ROMs themselves (after all, they would
only work in Heath equipment).
