(Insert ear-to-ear grin here; I was the lead engineer on the Tek Basic implementation.) The box uses the NS32016 chip and FPU, and the Basic "interpreter" secretly compiles to machine code when you type RUN. There's no hardware support for SQRT, instead it uses a tightly coded assembler routine. Of course, you have to run Unix instead of MS-DOS. -=- Andrew Klossner (decvax!tektronix!orca!andrew) [UUCP] (orca!andrew.tektronix@csnet-relay) [ARPA]
