What is this adapter for?

[eslapion]

Actually, I produced the MasC=uerade, and they are sitting here, but I never put them in the store. If there is interest and sanity (I never put them in the store because I was deathly afraid people would buy one and a EF3 and then yell at me that they could not replace their VIC-KERNAL with the unit), I will put them in the store.

Plugging an EF3 into a VIC-20 will obviously give nonsensical results but this begs the question... If the MasC=uerade is designed to allow people to plug C64 cartridges in a VIC-20, which cartridges will be supported (obviously, only a specific subset) and what will the result be and/or to what end ?
