Yup, but I beg to differ. A SIMM of course is a little baby PC board with RAM and an itty-bitty edge connector. SIPPs do exist, some PCs use them. They are like SIMMs, except instead of an edge connector they have a row of pins that go in a "real" socket. Look at many 386/486 clone motherboards for applications. SIPPs are popular for the same reason ZIPs are, since they are pins they can go straight in without the "tipping" in that SIMMs need you can get high MB p/sq in ratios. (Now *there* is a new spec). To be complete, SC DRAMs will work fine with Page mode DRAMs, you'll just always be using them in page mode accesses and not gain any benifit. Also, Burst in general (on any machine) does not require SC parts, only the 3000 because of its design. Other techniques (Interleaving, faster DRAMs, Nybble mode DRAMs, etc) can be used to speed up DRAMs enough. SC of course is uniquely appropriate for supporting bursting in particular. > -- > Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" > {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy > "That's me in the corner, that's me in the spotlight" -R.E.M. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Mark Gooderum Only... \ Good Cheer !!!
