SmartBasic Cart with Default Drive Select Dual Cart

A cartridge carrying SmartBASIC, with a switch selecting which drive the machine treats as the default.

Why drive select

• A modern ADAM may have a tape drive, a disk drive, a drive emulator, a FujiNet and a hard disk all attached at once.
• Which of them the software looks at first decides whether it finds anything. Being able to choose, from the cartridge, saves reconfiguring the machine for each.

Why a cartridge

• SmartBASIC normally loads from a data pack, which takes minutes on a good drive and may not happen at all on a tired one. From a cartridge it is there at once.

"Dual cart" suggests two selectable images on one board - a common arrangement in this catalogue's cartridges.
