V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
So after more testing, now the blitter seem sulky
It just locks up halfway through doing the test it doesn't bomb or anything... And yet I have never had any issues with the blitter with these boards that I recall anyway.. Possible it could be a iffy socket.. But these are problems are extremely difficult to track down

This happens when just the normal 68000 in place (stock system) tried 3 known working blitters.. resoldered the CPU & blitter socket

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
does it still work at 8mhz? You're certainly not having much luck tonight.
If it ain't broke, test it to Destruction.
Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
It's now a stock machine... so the boards died somehow.

Certainly feel your pain today! PSU maybe?

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
its my new red one

Oddly I just found out the half of the databus is pulled up next to the MFP, So thats been a long running thing nobody has ever noticed.. I changed the address and databus ones, or so I thought, to 2.2K, but D0-4 is on a pull up no where near the CPU, madness.. so will change that one now.. maybe get lucky.
EDIT:
Nope. Guess I will have to change the blitter socket

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
Socket changed, still the same
Never known a stock board be grumpy like this either
I only just kitted this board out like a week ago because my previous one died for no reason.. now looking on starting on a 3rd board.. geeze...

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
Tried a totally different machine, and still getting the same error... I think there is some issue with the diagnostic cartridge test itself
So blitter is now working on this other board (tested wit GB6) , but the one I actually trying to test the booster on this basically resets not long after I turn the machine on, so that does have some odd fault which obviously is not actually related to the blitter
But saying that, when the blitter is removed, the machine does work

EDIT:
and now the blitter is working in the machine it wasn't doing earlier , WTF is going on
Plugged the SEC back in and blitter acting up again

Re: V2.5 BOOSTER CURRENT PROTOTYPE STATUS (SEC BOOSTER)
Plugged the original SEC back in, same blitter issues... turned on and off server times, now its working fine again..
There has to be something screwy with the MMU wakeup states or something, because the fault changes from just powering off and on again it seems.. I can press the reset button loads and it doesn't make it better or worse, its only a power up issue... I'm really starting to hate the Atari MMU these days

EDIT:
Several turn off-on's and 2 bombs after the Fuji now.. oddly that was what TF's board was doing as well.. Power off a few more times, working fine again.
I'm also wondering if these are the issues I had with the PAK boards as it didn't work on my machines, but worked on RJ's.. I bet if I powered off and on enough times that would boot up as well..
