# Programming SRAM HI*RES, Part II

At this point, let’s give credit where credit is due. As you may know, SRAM HI*RES Extended BASIC is a collection of new commands that make use of a high-res core routine developed by Mr. [Wilf Rigter](http://localhost/indiv/wilf-rigter/). This routine is an invention anywhere as significant as the original “cheap video” system employed in the ZX81. Without this core routine, all the neat possibilities that SRAM HI*RES has to offer would be completely useless. With no other hardware requirement than a static RAM in the 8-16K region, this routine is what gives your humble ZX/TS a whole new look, not to mention new worlds of possibility.
