 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Running on a chipKIT Max32 Compiled Z80em (z80 emulator) and using a Level II Basic rom Captured writes to the video buffer and sends them out the serial port and serial in to keyboard scan have not done any speed test but it don't seem to bad

I'll have to endorse that Vasi. That is really amazing Ken. So the procedure is Z80 emulator thrown at ROM image, then fix up the 1001 other things that differ from the original I/O mapping. Does this now open up the PIC32 as a possible platform, for every z80 computer that was ever produced? Just wondering how the Microbee re-launch is looking now.

Not quite that easy Don. The more complex the system, the more complex the remainder of the emulation will be. A computer like the TRS-80 is easy. Microbee a bit harder. An MSX computer harder still (Colour hires graphics modes, sound chip, sprites etc) The difference with the Microbee launch is that it will be 100% legal (ROMS, programs, logos etc). |

I think that for the video and audio part can be used a second PIC32... or something else... Hobbit name: Togo Toadfoot of Frogmorton Elvish name: Mablung Miriel Beyound Arduino Lang |

Sure Nick, I realize that a lot of what is thrown around is hypothetical. The reality can be very different. Cheers Don... https://www.dontronics.com |

All that's missing is the battleship gray case.
Next step is to also emulate the hi-res graphics add-on. 
Can in run CMD files yet? I'd like to see it run some of my old M/L games I wrote. Nice touch using the original TRS-80 monitor BTW. |

This is all turning out like MAME for the vintage PC world! For crying out loud, all I wanted to do was flash this blasted LED. |

THAT'S AWESOME!!
Can it run on a standard Maximite? Its easier to ask forgiveness than to seek permission! ............VK6MRG.............VK3MGR............ |
