		Re: Simulink Compilation
Dear Marc, It would be very interesting to have Simulink + Realtime Workshop controlling the RCX. By the way, how much speed do you expect can be achieved considering the communication speed between PC and RCX ? Liem. (...) (20 years ago, 22-Jan-05, to lugnet.robotics.rcx.legos)

		Speed of RCX interpreting bytecodes: slow
While working on the barcode scanner I decided to see just how fast the RCX could loop. A simple NQC program can do about 1000 counter loop iterations in about 100 ticks, or 1 iteration/ms. This is shockingly slow. The native H8/329 is clocked at (...) (25 years ago, 1-Jan-00, to lugnet.robotics.rcx)

		Robolab/RCX program code size and limits.

		Re: anyone know how to check free space on RCX?
While the declaration for mm_free_mem is int mm_free_mem(void) The fact is that the RCX has only 32K of memory available. 32K in hex is 0x8000... there's never a need for more than 4 digits in hex.

		Re: Maximum Subroutine numbers?
I don't use Robolab, but I can offer some insight into how the RCX firwmare operates with subroutines (and events) that may partially explain your problems. RCX firmware supports 8 (eight) subroutines per slot. Internally they are numbers 0 to 7. (...) (21 years ago, 28-Dec-03, to lugnet.robotics.rcx.robolab)
