| | Floating-point bug fix

This morning, Kieran Elby sent me a report of a "0 - x" bug with subtraction in the floating point routines, which I fixed. In the process I reread the IEEE specs and decided I could do something simpler for both subtraction and negation. The (...) (24 years ago, 17-Dec-00, to lugnet.robotics.rcx.legos)

| | Firmdl3 updated
|

Following a discussion on lugnet.robotics on firmware versions and firmware checksumming, I realized firmdl3 was broken for the latest firmware files (firm0325.lgo and firm0328.lgo). The problem was these files were too big. I have modified firmdl3 (...) (24 years ago, 16-Dec-00, to lugnet.robotics.rcx.legos)
