Howdy, all the Scout byte codes are available at: (URL) will give more in-depth information and examples in the future, but all the codes are now there. Unlike the RCX, it looks like it is possible to get a program off the Scout. With the RCX you (...) (25 years ago, 26-Nov-99, to lugnet.robotics)

(...) I'm just guessing. If it has the upload data opcode, why not unlock firmware? On the RCX, there needed to be a specical code "Do you byte...etc" to allow the firmware to be "unlocked" and executed from 0x8000 hex. Now, the trick was to monitor (...)

(...) The Scout must have control programming somewhere. What interests me is that out of 1K of RAM only about 400 bytes is available to hold a user program. Could the control program be held (preloaded) in the remaining 624 bytes of RAM? Robert (...) (25 years ago, 26-Nov-99, to lugnet.robotics)

The pollm command lets you look at memory from 0x40 to 0x440 (1 K). The unused memory does not look like code. It looks like the system attributes are available there--probably battery level and such. Also variables must be there. We have 10 globals (...) (25 years ago, 26-Nov-99, to lugnet.robotics)
