Dr Andy Wright ran BetaSoft, a one-man software house through which he sold BetaBASIC: an improved version of BASIC for the Sinclair ZX Spectrum. When MGT were designing the Sam, they approached Doctor Wright and contracted him to provide the ROM and DOS.
BetaSoft also published many other Coupé titles.
An interview with Andy Wright featured in Sam Revival issue 14.
