You need slow, keepio and change keeper to float

Done that, made no odds.

Well dunno. i never had issues with ram on the ST... worked fine. :)

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...

CPU CLK50M, RAM ~CLK100M

Hmmm. Yeah leave it like that if its working then... i think later boards i have CPU and RAM at same clock rate.

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.
