(real programmers even don't use assemblers but code directly in hex)

Reminds me of BBC micros, where the most useful BASIC command was the open
square bracket to go into assembler!

Do you have facilities to program the RCX in assembler or hex?

I'm interested in a lower level language so that I don't have to learn another
higher one!  At the moment I program the RCX in VB using the OCX file but I'd
like to experiment with alternative firmware.

Since I soon learned that the way to squeeze more out of a BBC micro was to use
machine code, I think the same is probably true for the RCX.

Are the sensor port power/read cycle timing and the available motor speeds
dependent on the firmware or the hardware?

(...) Sure, that can be done. Take a look at brickOS. With brickOS as operating system you can write your programs with gcc. So you can write c, or mix c with assembler via asm{} or you could write plain asm routines. (...) But you have to learn H8 (...) (20 years ago, 7-Mar-05, to lugnet.robotics)

(...) You could certainly use assembler (and presumably hex) using brickOS but I don't think it's possible with the standard firmware. Of course a true 'Real Programmer' would just dump the firmware altogether and write to the bare metal. (...) (...) (20 years ago, 8-Mar-05, to lugnet.robotics)
