As if it weren’t nerdy enough, the 6502 40th Anniversary Computer Badge runs Lee Davison’s EhBASIC. There are __1024__ whole bytes free for your programs, so it’s not exactly spacious. It’s got useful floating point support, though:

Yup, that’s the *second* most boring BASIC example program, after the quadratic root finder.

100 REM HERON ROOTS 110 EP=0.0001 120 INPUT "X";X 130 N=1:RN=X/2 140 PRINT"COUNT","ROOT","DELTA":PRINT"======","======","======" 150 DE=ABS(RN*RN-X) 160 PRINT N,RN,DE 170 RN=(RN+X/RN)/2 180 N=N+1 190 IF DE>EP THEN GOTO 150

**Update**: Josh got my badge working again (it wasn’t, for *$reasons* …) and I re-ran this code. If you try the code for X=100000 and larger, it won’t converge. You might want to add:

185 IF N>25 THEN PRINT "EPSILON TOO LARGE, EXITING":END

so that the loop will exit after 25 times. Alternatively, make the value of EP depend upon the size of X. Aren’t numerical analysis and floating point foibles fun?
