This depends upon which CPU you use, if the external clock of the CPU is 60MHz or less (ie, 75, 90, 120, 150MHz CPU) they require 70nS memory. If the exteral clock is 66MHz (ie, 100, 133, 166MHz CPU) they require 60nS memory. Given the very small delta between 60 and 70nS memory I don't even sell 70nS memory anymore. If you wish to carry your memory to your next machine and you are buying a substantial amount of memory I would suggest spending the money to put x36 parts in now. Quite often when you upgrade it is a MB/CPU/Memory type upgrade and spending money now may not be such a great idea depending on how soon you plan to upgrade. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
