  This fork of the canonical git mirror of the LLVM subversion repository adds (e)Z80 targets. Please refer to the wiki for important build instructions. (by jacobly0)

  Very cool. While obviously not ideal, the results are probably accurate within a small factor. Unfortunately there's no assembly version for 65C02 but Z80 does surprisingly well in this test.

  I muse what could be done with modern cross-compiler (SAT solving for optional code sequences?) A llvm backend for Z80 has recently kicked back into gear: https://github.com/jacobly0/llvm-project

  Discontinued Arduino-based Operating System for Stern MPU-100 and Bally AS-2518-17 pinball machines. This library should be unpacked into a folder for a particular machine's implementation (Example: Stars2020).

  

  a lot of pinball machines are based on the 6800. i've been really impressed by one project that replaces the 6800 with an avr by just wiring up all the relevant pins and holding the 6800 in halt:

  i've started working on a derivative project using an rp2040 instead of the avr with hopes of offloading the 6800 bus work to a pio

  There is something special to me about the idea of writing modern C++, and compiling it for such early microprocessors. The 512 bytes of RAM is a pretty big limitation though. I wanted to try and emulate an EEPROM using an Arduino or FPGA, but got stalled out on the project. From time to time I like to browse through the LLVM backend documentation, but I can't seem to commit to trying to build a backend.
