Hi all, How do I turn OFF the auto shut off function of the RCX? I'd like to write a program which contains some long (1hr) delays. Thanks for replies, MTapsak (24 years ago, 1-Nov-00, to lugnet.robotics.rcx)

Rob, Did you ever get any answers to this query? I also have three of the newer Technic motors that have seized. (Out of a collection of about 10 motors that's a 30% failure rate - not good!) I suspect that this may occur with lack of use rather (...) (24 years ago, 1-Nov-00, to lugnet.robotics.rcx, lugnet.technic)

(...) Good idea. I saw I didn't paste the definition of RESET_BUTTONS into the message. Inside the interrupt handler, the Program key hides the Run key. So Program+Run=4 and Program+View+Run=6.

Hi all, as I am one of those people who cannot remember the order of the arguments to DUMP, I wrote a simple interrupt handler to use RUN as a reset key (like ctrl-alt-del on a PC). Comments are welcome here, or by email. Ernst Include the following (...) (24 years ago, 30-Oct-00, to lugnet.robotics.rcx.pbforth)

Hello, (...) No they don't have a separate address space. I think the limit is 19456 bytes for the kernel, and this is caused by a limitation of the ROM, which is used to download the firmware (kernel). It loads it to the address range 8000-cc00. (...)
