Berkeley Sprite Project Lines: 24 The 30-286 can take up to 4megs of RAM on the motherboard. It can take either 1meg simms or 256k simms (however these are slightly different from the standard simms, ie make sure you buy 30-286 simms, they are also slightly more expensive). The following memory configs are legal: 512k (2 256k) 1024k (4 256k) 2048k (2 1m) 4096k (4 1m) No mistake above. These are the only valid motherboard combinations. You can't do 1536k etc. You can also add AT memory expansion cards. However, look for short AT cards. Full AT height cards (bigger than XT or PC case) will scrape the side of the 30-286 cabinet possibly causing damage to your card, case, vertical AT bus thing coming from the motherboard.
