this is strange ; at reset, I set dma start / dma end addresses to 0 
(TOS 1.62 doesn't init them during boot).
Did you use tos 1.62 or 2.04 ?

after booting to gem desktop, could run a small program to read 
ff8903/05/07 and ff890f/11/13 ? (from monst maybe)

Hopefully, if TOS doesn't init dma start/end, we should have the value 
set during reset.

Also, if you just run the 3 above instructions from devpac after 
booting, does it start to play noisy sound or just silence ?
