Re: GS memory expansion

["Jim Thompson" <pdsrome@roman.net>]

Since 41256 chips don't all say "41256", is there a good resource that will
tell you which manufacturer's chip is a 41256? Or is there a particular
number pattern that exists? I'd prefer not to have to buy new chips from
Jameco when I'm sure that I've got loads of these chips sitting on old PCXT
mem cards or motherboards. 

Also, did Apple only make 1 or 2 meg cards? Is there a way to tell which
card is which? 

thanks
