I wanted to have a usable Z80 running its own code, with the teensy supporting it providing the RAM, I/O peripherals, and clock. Very interesting. It’s only the first part; the second part is available too!

Anachronda 2015-01-12 4:07 am EST Following the link the in page to the technical info for the Teensy being used, I see that it’s a Cortex-M4 with enough memory to run a Z80 emulator.I wonder whether emulation would be faster. galvanash 2015-01-12 5:18 am EST I wonder whether emulation would be faster.But where’s the fun in that?He didn’t even provide a real clock – he was faking a clock signal … I don’t think fast was one of the objectives. joshv 2015-01-12 3:29 pm EST He’s really emulating a custom Z80 chipset here, I/O and memory. h5n1xp 2015-01-12 2:04 pm EST The Teensy 3.1 is a brilliant device, so powerful I use it a lot for interfacing old 5v chips with other more moden devices.
