  Those are EASY to find. Just go to a surplus store and grab the old VGA
type video cards. A lot of them used those chips and they're frequently
socketed. You need to check the part numbers, the 4 x 256k chips are
available with a number of different part numbers but the PNs are usually
some variation of xxxx4256-xxx.

    Yeap :-) I use them in my HP Viper cards. I picked up over 200 of the
ICs in video cards in one trip to a surplus store.
