    CyberMaster memory limit? —Fredrik Glöckner
   I've been playing around with programming the CyberMaster unit with NQC. I've noted that when the size of the program gets too large, the execution of the program fails in some way. The way it fails is sometimes somewhat inconsistent. I don't know (...) (26 years ago, 28-Nov-98, to lugnet.robotics)
   
        Re: CyberMaster memory limit? —Laurentino Martins
     Your program generates a .RCX file of 440 bytes. I've created one with 452 that works OK, but had to stop around that number because after more 2 or 3 lines of code the last task simply disappeared (my program had 1 main plus 3 tasks). I guess the (...) (26 years ago, 28-Nov-98, to lugnet.robotics)

      (...) Thinking ahead, and also if I recall because the set had the idler gear in it, I bought several of the rubber-skirted hovercraft some years ago.
