I put my hands on two spare HDMs and by chance both are quite interesting.
One is built on a standard 07p PCB, but it is missing the coil switching relays and also missing half the adjustment coils (and some other less aparent stuff as well) the board number is 03-270353-01P. The board is from 1996, I believe it is an early Marquee 9500 (or 8500) DM projector, with the scan limitation to 65kHz, therefore no apparatus were made to run the scan yokes in parallel mode.
The other one is also interesting: That is from 1997 and is built upon the 08p PCB, so it should be believed to an ULTRA HDM, but it is equipped with the smaller old style heat sink and the board number is 03-270303-08p, whereas an ULTRA HDM should be 03-270303-09p and the regular one is 03-270303-07p. This board uses the old style FETs too. Any idea what could this be?
Here is a picture of the DM style HDM:
