No, the frame counter in the ZX80/81/Spectrum (if yours is a ZX80 rather than 81, I'd like to buy it, BTW) simply counts the TV frames it produces. Those, in turn, would be about 60Hz in (...)

| I'm reasonably sure adjusting the IR carrier wave frequency would require hardware modifications. The baud rate can be adjusted. I've seen a couple posts stating that 9600bps makes the communication really picky. - Rob ----- Original Message ----- (...) (21 years ago, 15-Apr-03, to lugnet.robotics)

| The frequency of the RCX's IR does not change at all: " The RCX uses a 38kHz carrier, which is pretty typical for TV remotes. As for the sampling rate, the RCX runs at 2400 bps, which makes each bit approx 417us " (URL) think the only way you could (...) (22 years ago, 28-Sep-02, to lugnet.robotics.rcx.legos)
