| | | (...) I have beta quality Tcl code that sends an SRECORD firmware imge up to the RCX (fast or slow) and has basic terminal capabilities. It also strips comments and whitespace out of files as they are uploaded to reduce the time. I'd like to put a (...) (25 years ago, 4-May-00, to lugnet.robotics.rcx.pbforth)

I don't remember the details but obviously it stayed with me. Besides all protocols tend to look the same at (...) (25 years ago, 4-May-00, to lugnet.robotics.rcx.pbforth)

| | | | (...) I believe that. 32k of RAM is a luxury for forth. That's another thing people don't generally understand about forth, they way it effectively compresses runtime software. I've heard of ram reductions of a factor of 5-10 for forth when compared (...) (25 years ago, 5-May-00, to lugnet.robotics.rcx.pbforth)

NOTE WELL that there is a subtle bug in the RCX ROM routines when (...) (25 years ago, 5-May-00, to lugnet.robotics.rcx.pbforth)
