No hope for me then :) only works if I invert the RAM clock.. TTRAM does drop a bit in speed, 903% to 847% or something like that.

is your ram clock set to 100Mhz, 50mhz or CPU clock speed...

Looks like 847% is the "proper" speed anyway... Mine must have been running too fast for some reason to get 903% originally.

When high it is either accessing ROM or TTRAM... If it is pulsing low, it is accessing the ST bus.. which is not all that often now :)
Yes! That's *got* to be the tipping point.

Should not have been seeing all those AS30s on the ST side.

DSTB1 Open source 16Mhz 68k and AltRAM accelerator for the ST
