This is now fully hacked-in and tested! https://modelrail.otenko.com/retro/power-mac- … atible-midi-out

Talking to myself, it occurred (to myself) that I could just find hi-res images on Google and trace the traces. I've managed to determine MIDI-OUT Pin 12 is hooked to the 11-th pin 'up' (aka Pin 30) from the bottom-left of the CT2501 when looking at it with the text level. In the images, blue is …

I got the card in, and indeed MIDI-IN / MIDI-OUT / 5V / GND can be toned directly off the Vibra chip with no discrete components between the chip and the gameport on the back of the card. My next step is to find a second DOS Card Vibra module (so I don't sacrifice my original) and create an adaptor …

wh000... so it turns out having the cpu on auto cycles causes the stack error on resuming of the debugger... strange. Anyway, problem solved... I got the bugs out and I can build all the vehicles I need to in TTD under DOSBox. I'm still keen to take this debugger places though!

Code view and overall font... I'd love to get this into a GUI or shrink the font and have more rows and columns... edit: Thoughts on some sort of hook (tcp?) into dosbox to be able to remotely browse the code/data memory?

the actual dosbox_debugger window. I'm perousing through the lines of assembler for our patch and trying to work out why the DOS verion of the game is crashing. (It has been tested and works fine usually, but due to a 'feature' added by 'someone', there are now bugs and I need to squash them!)

To the folks of DOSBox, you've done an amazing job, DOSBox is an awesome piece of software. I've recently been developing with the team at TTDPatch to enhance both the Windows and DOS versions of TTD. Windows is fine to debug, OllyDBG does everything I need... But debugging a DOS application has …
