We do not know what capacity it is. It came from a Display Station with both a memory card in Slot E and a Memory Extender Card in Slot F. If this was the factory configuration, then it should be 160K, 192K or 256K, but we do not guarantee any specific capacity at all.
Consignment sale for a collector who is downsizing. The consignor's notes say that when last tested, some years ago, the system got as far as a keyboard error, because he did not have a good keyboard at the time. Because vintage components can fail at any time it is sold as-is, officially "for parts or not working" with no guarantee of functionality or completeness whatsoever. Listing is for the card only, with no other accessories.
This is the only one on the market - don't let it get away!
