I don't understand why people seem so interested in this. Why would you want to slow down the pi to emulate another cpu when you can run it as a native arm machine?PiyoTaro wrote: ↑Mon Mar 11, 2019 8:08 amSince it seems that the article of "co-processor" to which David Ball was posted on February 26th (during this period) is not interested, so I would like to repost this post.

I can understand it on a bbc machine as it had this tube thing from the beginning to allow another cpu to be used in the machine. You had to have a z80 to run cp/m to be taken seriously as a business machine. So taking this tube thing to its logical conclusion you can put really fast versions of these cpus on it by emulating them in a pi.
But on a next what would be the purpose of having a 100MHz z80 emulated on a pi when you could be running the pi as a 1GHz Arm??
