"True parity" means it really has the extra memory chip to store the parity; some SIMMs use "logic parity", which just calculates a parity bit when the memory is read. Crucial (aka Micron) has this stuff; http://www.crucial.com. Their prices are somewhat high. Somebody on the list a while back reported that Mcglen is a good place to get parity memory; http://www.mcglen.com. Their prices sound a lot better than Crucial. And of course there's always eBay, Onsale, etc. The four 16 MB SIMMs in my AS200 4/233 came from Onsale.
