Re: Blank cartridge boards Script/Plus and Calc/Plus are cartridge-based. And the 3+1 ROMs work in a cartridge, if one is so inclined. We also have the Speech ROM (not that it would work, since the custom circuitry is still missing) and some aftermarket operating systems like New-ROM, OS96, and JiffyDOS.
