       "A friend of mine just bought a used "H-89" computer (a
       Heathkit) that runs some form of CP/M.  I'd like to give him
       some PD software ..."

The original H89 design put ROM at location 0, and a special CP/M was
created which could accommodate this.  (The same hack was used on the
TRS-80 model III.)  Standard CP/M binaries will not work on such a
system.

There was a mod to the H89 later which made the ROM shadow-able and put
RAM at 0.  Before you spend a lot of time moving your software onto H89
disks, you might as well find out if it has the mod.
