I should be able to try this easily too. Actually I was thinking of something like that, as PHI2 (HI) is also used for allowing R/_W.. Check the datasheet if there is a minimum time between _RFSH going high and the next read or write access to the RAM happening. If yes, is it short enough for the VIC-20?
