The difference is: the PS ROM card and an additional RAM card or a PS ROM card with integral RAM. The PS feature came both ways. RAM for HP printers is standard RAM, but with parity. Also, it has to be fast RAM, 60 ns, IIRC. The RAM is easy to find as it is standard PC RAM from back in the 386 and 486 days, when every PC supported parity, but the parity could be turned off in many PCs. In an HP printer, parity may not be turned off, so the RAM sticks have to be 36 bits, not 32 bits. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
