Porting this program to another Z80 platform should be easy and straight-; forward. The serial data port will be very easy to implement with the teensy Serial object. But that may take a while. The compact flash card interface is exactly the same as normal except instead of using 16-bits of data the card exchanges 8-bits of data at a time. The X bits are all at the bottom - so moving across the screen is easy, but moving down is a pain - so long as we're in an 8 pixel tall strip (effectively a character block) we can just INC D, but beyond that we have to do some work! the top 3 bits are always %010 - because the screen base is &4000. The Z80 Assembly extension for Visual Studio provides the following features inside VS Code: Syntax Highlighting for Z80 Assembly; License. I will make the changes I proposed above, push the code to Github, close off this experiment and clone to a new directory for a single assembler version. Firmware, RomWBW To summarise RomWBW, I’ll quote Wayne Warthen, author of RomWBW: RomWBW is a ROM-based implementation of CP/M-80 2. Simulates all pins of the Z80-Chip in a single function interface.
