Well as far as I can tell the blitter is off.
It is off in XBOOT.
NVDI .CPX seems to have no control for it.
Gembench reports 47% as blitter speed relative to a Falcon (and there is no
problem carrying out the test).
[No doubt dependent on Nova screen resolution and depth]
I also checked/cleaned the keyboard connector with no apparent difference made.
I have preeviously run Doug's mmove patch over everything I could so I don't
think it is that either.
The hang symptoms and mouse jumping did sound to me as if they could be the
blitter. With AB040 and Nemesis fitting, would the blitter have been definitely
physically disabled or is there a risk it is sitting there and interfering with
blitting by 'waking-up' every now and then?
Maybe I'll just try and get on with software updates and hope it goes away.
