RAM USERS BEWARE!!! The Fujitsu version of the 4416 (16K X 4) DRAM as qualified under Atari part number 137323-001 will not work in a board with a RAS/CAS generator designed like the one on Crystal Castles. The CAS HIGH to RAS LOW delay time on both the TI and INMOS parts is specified as 0ns, while the Fujitsu part needs 30ns for the 150ns version. On Crystal Castles, the CAS signal clears an S74 to generate the leading edge of RAS. No way can it work. I have asked that Fujitsu be disqualified for 137323-001. Ross Cox
