128 K RAM Card for ][ Plus

[gareth@freenet.vancouver.bc.ca (Gareth Jones)]

Can anyone tell me about a Slot 0 memory card for the Apple ][Plus that 
has 128K of RAM? It doesn't have a cable that connects to the 
motherboard, the way some slot 0 cards did. It is a full-size card. There 
are 4 red LEDs on the top (for banks of RAM?). There's no manufacturer's 
name on it. The largest chip on it is by Motorola, and it has the 
following identification "MC3242AP" then "QQ8327" on a separate line.
 
I'd like to emphasize that it's working fine as a 16K language card, but 
I'd like to find out how to access the rest of the RAM for a ProDOS 
RAMdisk. Any ideas?
