How about a Forth based environment running on the PC? It would not be that difficult to move the RCX based compiler to be a cross compiler on the PC. One would be able to run in two modes - "native" through a Forth based terminal (...) (25 years ago, 2-Jan-00, to lugnet.robotics.rcx.pbforth)

How about a more generalized interface to the pbForth system. Although Ralph Hempel believes this to be unnecessary, I find the RcxCC interface quite appealing. Harald Striepe (25 years ago, 2-Jan-00, to lugnet.robotics.rcx.nqc)

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)
