MCS BASIC 52 is a powerfull software tool , capable of managing aBASIC high level programmation of all Intel 51 family based cards. Itis a "romated" software that generates "romable" software in an easy touse enviroment; it also reduces the necessity of external hardware (incircuit emulator, EPROM programmer, etc;) and at the same time itspeeds up debugging phase of the User application program.MCS BASIC 52 is referred to generic software tools, but each cards hasa specific version of software associated to their hardware features; sofor each card the name MCS BASIC 52 become BASIC followed bythe card final name.
