Except that... Memory requirements are huge. The needed registers seem in the range of 2.5*R^2 at bare minimum. For R=30 you need something like 18Kb if each register takes 8 bytes, plus extra variables, plus program stack... So you need something like 20Kb RAM. This rules out the 41, the 42, the SHARP pc-1261... You need a 32K machine basically!

I ported Fernando del Rey's BASIC program to my Sharp PC-1500 with 8K memory module (10k total storage). It ran the size 5, step 6 case easily. I ran a 10/20 case (took just a couple minutes - didn't time it). When I try the suggested size 30, 60 steps case, the computer unsurprisingly gives an out of memory error. Trial and error shows that I could go up to a grid size of 23.

Excellent, thanks !
