SNES SFX MULTICHECKER-01 pcb, like Campus Challenge?

I've got some weird SNES DEV PCBs. The case looks exactly like this well known one:


If I'm not wrong, it's even similar to the one used for SNES-CD prototyping. Anyway, this is what I've got (sorry for the quality of the pitures):







No EPROMs, just empty boards. On the top shell there is written (on the label) "SHVC MULTI CHECKER-2021" while on the plastic "Nintendo Super Famicom".
The closed case is shaped like a "T", just like the Campus Challenge/ Power Fest.

What were these used for? I'm asking because I'm used to see protos on a very different variety of boards...

Thanks!
