Hi Dave

 I believe that all of the required operations of the H17 can be
accessed through the jump table at the begining of the ROM. Look
at the listing for these. This is for HDOS. For CP/M there are
similar tables in the BIOS.
 The only things that might not be obvious are the timeout timers
used by many of the operations.
