Some small progress. Segment 3 ensures that program execution starts at address 0x200 by overwriting the character input hook. Segments 4 and 5 loads at address 0x200 and contain some kind of loader. I need to look into the details here, but it looks like it messes with the SAM and moves all the pro...

Magnificent! Thanks for your help, Alastair. I now have working CoCo emulation

Thanks, Alastair. Still haven't been able to get it to work, though. Now, bas10.rom is the only ROM file I have in my xroar directory and I start xroar without parameters. The stderr.txt file tells me that xroar starts in CoCo mode and loads the bas10.rom image. Same result as before... I will inves...

Guys, I have a really embarrassing question... I'm trying to set up xroar 0.25.3 to emulate a CoCo for some testing purposes. I have downloaded and renamed roms from the forum and tried running xroar in many different ways, including something like this: xroar -machine coco -bas bas11.rom -extbas ex...

Days quickly becomes weeks, but here's an update on how this mini-project is going. Not being a CoCo expert, I learned a lot of new stuff when actually starting to parse RSDOS filesystems... The RSDOS way of storing machine code programs is way more flexible than DragonDos, so a simple 1:1 conversio...

Thanks. Will be fun leafing through these old rags again

Fantastic stuff!

Nice

This is a pretty good design from Hot CoCo (June 1984). This is a relatively simple to build interface for switching joysticks that even provide "autofire" functionality. The ICs are pretty standard and easy to obtain even today. There are some minor mistakes in the figures, and it might just be pos...

Briza, The tools should run on any Windows version where the .NET 4 framework is installed. I am primarily testing on Windows 7. Currently, this stuff is highly experimental and only a single command line utility is provided. I'll get around to some GUI programming once I get the time. As this is st...
