*LOL* Overclocking with 32 MHz clock reminds me of the experiments with my 500 in 1990 or so... My 15 kHz monitor was screaming but everything else was fine. :laughing:

SuperBuster was designed to run @ 28Mhz. Some users have overclocked their motherboards past 33 Mhz. This mod only increases the clock to the Zorro2 logic in SuperBuster to 14 Mhz. Thats hardly overclocking!

Yes please elaborate. I wonder if the 2091 will be fast enough for the Vlab Motion now??

@Tension
All is explained on the EAB thread. Just follow the link in post #1.
 
@magnetic
This mod does not speedup Zorro2 DMA or alter Zorro2 device timing. It's a simple fix to enable SuperBuster to run Non-DMA cycles at full Zorro2 speed. (approx. 3.5 MB/sec). It will speed up buffered copymem cycles on the A2091 if you have Zorro2 fast memory installed and use Vbak2091 (Aminet) or Ralph Babel's Guru ROM.
