Help Identifying Tandy Memory Expansion

Does anyone know what system these boards go to?

Maybe the Tandy 5000MC? I think that was the only Tandy with special memory expansion cards using SIMMs.

http://ohlandl.ipv7.net/tandy/Tandy_5000mc.html#Memory_Card shows something with 8 SIMM sockets and a connector with 2 sets of fingers.

Shows that board, and has a reference number that's listed on the board itself!

Was also used in the 3000NL I believe

the one on the left is for a Tandy 5000, the one on the right could be 3000NL or 4000, need to see markings on the board itself.
