Title: GEOS at a higher speed
Post by: RobertB on February 10, 2011, 03:06 AM

Hello, everybody, and especially GEOS gurus!
I just received an inquiry from CBM engineer, Bil Herd. He wants to know "how well [you] think the GEOS code would work at 12mhz...". That is, if there is "access to local static ram @ 12Mhz (gets written to C64 dram by caching mechanism)" and "access to I/O â€" 1 Mhz".
If you have an answer, please post it here, and then I will forward the message to Bil or direct Bil to this thread.

Thanks,
Robert Bernardo

I think it would work very well. Somebody with a SuperCPU could probably tell you for sure. It sounds like the same concept to me, from what I know. Of course the SuperCPU is a bit hard to come by and rather expense when it pops up, so if he has something new in mind, that would be great.
