It depends on what model of 3000. The 3000/300's do take 72pin parity 
memory. the other 3000's use very proprietary modules to support the 
super-wide memory channels. I've used regular simms in my 3000/300 with 
no trouble. I think they were 70 or 80 nanosecond. I think if theyre too 
fast, they will run into some troubles, dropping bits, so i'd say keep 
them around 80 ns or maybe 70.
