Umberto Posted September 20, 2016 Share Posted September 20, 2016 Having problems installing v2.2 booster on my Rev 5 mega st4 mother board, It hase no R150 to bypass. have replaced all the imp chips with chips from some stfm's. replaced all the 4.7k resistor arrays with 2.2k ones. It is still unstable. boots to desktop in tos 1.4 and 2.06 but crashes on disk access and when I attempt to turn on the blitter. I socketed the cpu and reinstalled the original 68000. It works perfect and passes all ram tests ect. HelpRob Quote Link to comment Share on other sites More sharing options...

Justin Payne Posted September 20, 2016 Share Posted September 20, 2016 Ah, he's speaking Washingtonian. I speak most dialects fluently. I went to the website and it looks to me that with the Mega's you need a MEGA BUFFER board. You don't mention that in your post so I figured I'd ask.

I installed it, I actually got it working this morning, had to repair the trace that Atari cut when they installed the blitter patch, on the backside of the board. Washingtonians!!! I would feel insulted if I knew what that meant Quote Link to comment Share on other sites More sharing options...

Justin Payne Posted September 20, 2016 Share Posted September 20, 2016 Your profile says you're from Everett Washington State, hence you're a Washingtonian. Quote Link to comment Share on other sites More sharing options...
