Problems with Verilog bit array.....

Hi all, Posting this here too as I know some of you also use Verilog and may have some useful input, also since the 6809 bus is similar to the 6502 bus that helps too.... I'm making an addon for an old 6809 based computer, one of the components of this machine (Tandy CoCo) has an IC that is programm...

Re: 6809 experiments

An Atom might be a good start to write your own mos. The Atom is a simple machine and it's also very well documented. In fact, back in the 80's some people were actualy replacing the 6502 by a 6809 but they never published their software. Please keep us informed about your projects. It also has a 6...

Re: Acorn Atom Emulator

Also Feel free to take the implementation details for the RamRom, Gdos2015 from Atomulator.

You'll have to ask sirmorris about the AtoMMC code, but he didn't have any objection to me building it into Atomulator, but you should probably check with him just to be on the safe side.

You can't access the PC OPL chip directly in Atomulator. This is possible in Wouter Ras his emulator v1.33 because the PC I/O addresses $0000-$03FF are mapped to the Atom addresses $B400-#B7FF.
