Unlike Sinclair's previous foray in to the computer hobbyist market, the MK14, this machine would ship with BASIC, based on the ANSI standard. But the aim was to keep costs down and that precluded paying a licence fee to Microsoft. To this end, Sinclair had already met with [[John Grant]] of Nine Tiles in April to discuss the software requirements of the ZX80.
