(original, older post)
TI-Benchmark has been rendered useless on newer calcs/AMS versions, so I made ti68k-clkfreq. The core principle is actually really simple: in ASM, it puts 55555554 in d0 and repeatedly subtracts 1 from it until it equals 0. Then it exits. And the amount of time that loop takes to run, in seconds (Δt), is enough information to know the clock frequency of the 68K in MHz: (1/Δt)*1000. The fact that background interrupts remain running is accounted for. For accurate results, refrain from pressing keys while the measurement program is running.
I released a new version of my program last night that lets you use it programmatically, i.e. without creating any dialogs or requiring any kind of input.
Figured I'd post a thread about it here because "my project" belongs in the "Your Projects" section of the forum, 0x5
