I am looking for a peculiar 1Mb SIMM for a Philips model P 3302 '386 PC. The part is very similar to the 72 pin SIMM used in some PS/2s only this one only has 68 pins. These SIMMs have a 0.05 inch pin spacing. The PS/2 SIMMs are 256k X 36 bit, ie. double word plus parity on each byte. The Philips SIMMs we need are 256k X 32 bit, ie. no parity. This would account for the lack of pins. Otherwise the two parts look identical. Does anybody know anything about these, I'm sure they are a standard part but Philips locally are charging a ridiculous price for them given today's RAM prices. Conor Nolan Microelectronics Dept.

Try looking for SIMMs for the MAC. Yes, Apple MAC that is. They don't use a parity bit per byte. However, I am not sure, whether you can get exactly the same SIMMs. I once saw a list from a german dealer which includes 256kx8 bit for MACs. The newer MACs should have the chips you are looking for. >Conor Nolan >Microelectronics Dept. Fon: +353 1 772941 >Trinity College. Fax: +353 1 772442 >Dublin 2.

NON-parity SIMM's are also available, check ads in computer shopper, or other magazine. You want ones designated 256 X 8, or 1M X 8.
