Re: BLITTER RE-CREATION THOUGHTS

Wow, looks awesome. That must have involved some layout voodoo? :lol:

Re: Curt Vendel...

I read somewhere that he was born in 1966... so about 53 or 54 years old.
Very tragic indeed! RIP, Curt!

A bit of manipulation and we now have a slot-in rear panel allowing different panel layouts.
Slick! That's pretty awesome!

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...

Just thought I would share some videos of the FPGA Blitter Board running using the stock code at different clock speeds and the effects it has.

Running @ 8MHz

Running @ 16MHz

Running @ 32MHz

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. I have a side project idea on the go to recreate the Nova VME and ISA board as one inside the TT / Mega STE with the metal shielding removed so ...

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. The problems starts on the same frame, so it seems like your i-cache is disabled (by hardware) or malfunctioning. It's not due to software control as in the released v...
