Re: BLITTER RE-CREATION THOUGHTS

On the schematics, it can be seen that the HOG counter counts the XASI signal (incoming AS when the CPU is the bus master, outgoing when the Blitter is), that's how many times the CPU/Blitter accesses the memory. Yeah, it's not implemented this way in Suska. I spent so many hours to find a bug in m...

Re: Nova GPU Case

I have been mulling the Nova fit within the TT and MegaSTE for sometime now and the Nova VME board with the ISA board is quite a lot of overkill in space.

Re: Low Performance Falcon

Wietze, I forced the i-cache off in our JOY demo and it then behaves exactly like the video you sent me of your computer running it.
