3B1/7300 Memory Expansion Cards

[David Vernon Warnes]

I recently aquired a 3B1 from a friend and found 1 memory expansion 
card in the system. Question .. Can I take this 512k Memory Card and
modify it in any way to use 256k Drams. I am new to these machines and
any help would be greatly appreciated like places to get parts and any
other modifacations to the system to make it better.
