The memory or program cards that go into the side slot are impossible to find - if they were ever made in any quantity. The internal memory expansion for storage is easy to do. I think I contributed the WP2 manual on Club100 years ago.

In fact you can easily expand it for a low price. I can give you the chip information if you want. I'll just have to look it up. It's worth noting that I was able to pick up a transfer utility for the WP2 on ebay. Haven't tested it yet though. Take care, Louis
