It's funny but I've been driving a Z80 with an arduino-mega recently, and I actually timed it for the first time a couple of days ago. I'm getting 6000 clock-cycles a second. 6Khz, rather than that 6Mhz it would be cable of running standalone.
- kristianp 7y agoWhy is it so slow?
- stevekemp 7y agoMostly because I'm doing a lot of manual work reading/writing to the address/data-bus and there is some overhead in the code I've got for emulating RAM & I/O code. It should be faster, and could be if I reworked it. But I'm mostly using the arduino as a crutch right now until I get hooked up to real driving circuitry so I'm not overly concerned.
