[M100] Tandy WP2 Memory Expansion chips HM628128BLP-7

[Mark Wickens]

I forget what you do with these (replace an existing memory chip or 
insert in an additional socket) but they increase the stock Tandy WP2 
memory. IIRC they are static RAM chips.

I have three of them HM628128BLP-7 free for the cost of postage from the UK.
