Hi All,
Joined up to share a use of the Teensy 3.5 for interested people.
Basically I have created a daughter board (a few designs but 2 stable, 1 discrete logic based, 1 CPLD based) to relocate a Z80 processor in Sharp MZ series computers (but could equally well go in any Z80 computer) and act as the I/O processor and provide SD card services, real time in-situ monitoring and debugging and ability through detection and interception of making the host appear to be another machine.
The project is at https://eaw.app/sharpmz-upgrades-tranzputer-sw/ if anyone is interested, the source code in github at https://github.com/pdsmart/tranZPUter/tree/master/software and https://github.com/pdsmart/zSoft . Feel free to use any code if it helps your projects.
The Teensy 3.5 is great, the only complaint I have about it is assembly when using the underside pads, I've wasted a few boards trying to assemble them as my design needs most of the I/O.
Phil.
