Upgraded #Versa64Cart diagnostic cart. Now with "C128" mode. It just bothered me somehow that half of the EPROM was unused... Thanks @svenpetersen191 for very helpful comments ๐Ÿ˜€... And I have an idea how to close the housing now without cutting a hole.

โ€œDiag cart from @svenpetersen191 ... I wonder if I add R2, remove the JP8 jumper and add a switch for A15, theoretically I can insert an EPROM with 8 ROMs. Right? Anything else? #commodore64 #commodore #c64โ€
