Here is a little page (actually two pages) of notes and stuff from Mindfest. No pictures - that's already been done. The summary of the 2 (or 3) days is: (URL) and the text of my opening remarks is: (URL) Have fun... Cheers, Ralph Hempel - P.Eng (...)

Ok. You have heard me blather on about how I will eventually get the mazewalker posted. The code isn't posted YET, but the pictures and text are...here's the link. (URL) This is a complete maze navigation system. It figures out where the boundaries (...) (25 years ago, 13-Nov-99, to lugnet.robotics, lugnet.robotics.rcx.pbforth)

Sergey, I'll add the other basic wordlist stuff to the kernel, then I'll let the users "build" the optional system to their needs. In fact, I have three extra files that I assemble into a complete kernel. The RCX definitions (all assembler) (...) (25 years ago, 13-Nov-99, to lugnet.robotics.rcx.pbforth)

Hi Ralph, (...) Well, I meant that I know how to do it, but not yet tried ;) Also, it shouldn't be so difficult, so I will try it now. (...) Thanks for "really good forth coding", I can only say "I did my best" ;) Seriously, manage it as you think (...) (25 years ago, 12-Nov-99, to lugnet.robotics.rcx.pbforth)

(...) Oh, you mean that you can save the system dictionary up to the point of the SAVE_SYSTEM stuff that is at the end of the dictionary? Great! (...) I think a SAVE_SYSTEM script that is loaded in just before the system is to be saved is right. I (...) (25 years ago, 12-Nov-99, to lugnet.robotics.rcx.pbforth)

(...) Also, it is possible to create an alternative SAVE-SYSTEM word that will generate image without SAVE-SYTEM support included (similar to MARKER word). (...) It would be great. I would like to have it in a standard distribution. Only thing, in (...) (25 years ago, 12-Nov-99, to lugnet.robotics.rcx.pbforth)

(...) <snipped pbForth code> COOL! I guess you could load this in just before you actually need to do the dumping of the memory. This is a great contribution, Sergey. Do you mind if I put it in script format and package it with the standard (...) (25 years ago, 11-Nov-99, to lugnet.robotics.rcx.pbforth)

Hi Ralph, Finally I got it to work. Now there is XMODEM protocol and S-record writer on top of it. SAVE-SYSTEM word has been redefined to produce S-record image. Although upload time is up to 5 min now, instead I don't spend time anymore to mess (...) (25 years ago, 11-Nov-99, to lugnet.robotics.rcx.pbforth)

(...) The >R and R> words are used as little helpers. The put (or get) the top element of the data stack to the return stack. As long as you dont fiddle with the return stack between uses, they are a great way to do this. The alternative way to code (...) (25 years ago, 11-Nov-99, to lugnet.robotics.rcx.pbforth)

(...) Great, much more generalized code. What are the >R and R> words BTW? Did FFB7 C@ . and found the contents to already FE, as in, it appears that the default IR mode is indeed Long to start with. Seems like the effective range is much shorter (...) (25 years ago, 11-Nov-99, to lugnet.robotics.rcx.pbforth)
