How does zeroing out the first byte of the DECB range help anything? All 
that'll do is stop extended basic from initializing DECB.

For a proper cold start, better to EXEC&H8C1B (35867) on a coco3 - that 
will actually trigger the internal boot rom. 40999 (A027) does not. 
Triggering the internal rom will recopy the ROMs to RAM which may be 
helpful if you messed something up.
