| | RE: installation problem!
|
| (...) Ummmm, I think if you use NQC command line, the counter only goes to 1300 or so. I wonder 1f RCXCC is reading the SRECORD file and padding it to 16384 bytes. I wonder if it is actually loading the old firmware. I wonder.... Cheers, Ralph (...) (25 years ago, 29-Jan-00, to lugnet.robotics.rcx.pbforth)

| | RE: How much memory finally? ADDENDUM
|
| (...) There is no user memory from 0x4000 to 0x8000 - It's all ROM space but it might not be used. I look at things in terms of replacement firmware, and the RCX is very flexible in this regard. The RAM for replacement firmware starts at 0x8000. (...) (25 years ago, 10-Feb-00, to lugnet.robotics.rcx)

The standard rate is about 333hz, so debouncing would likely reduce the effective rate to 166hz, which limits the max rate at which the (...) (25 years ago, 25-Feb-00, to lugnet.robotics)

At DM 109, even the Droid kit is a good deal, not even counting the (...) (25 years ago, 6-Apr-00, to lugnet.robotics.rcx)
