It's really a shame that the Hercules Graphics Card didn't support a graphics mode that allowed for mixed high and low intensity pixels. As I understand it, it certainly had the video memory for it. That, combined with dithering, would have resulted in even more amazing high-res monochrome graphics …

Yeah, with some intelligent circuitry in between the the ISA bus and the non-VGA LCD controller, I guess it could work. It could then also handle things like scaling non-native resolutions and such. But it would also add more complexity and make it more expensive.

I have a quick thought about the graphics in the book 8088 and the possible use of only using a LCD controller for graphics? I know there is a new version of the book 8088 that uses a real VGA controller. I only found out recently about the new VGA version and had this thought before I knew the VGA …

I hope you can get it fixed! I haven't used my MT-32 in ages. I've been wanting to hook it up to a system for some retrogaming, but I kept putting it off. If they are prone to certain failures over time, I'd like to learn of them as well. Good luck.

I use a MT-32 pi regularly (as well as a real MT-32!) with my WeeCee and you need some sort of cable to bring the MIDI data from pin 12 of the WeeCee joystick port to the appropriate pin of the midi IN cable of your mt-32pi.

Interesting. Thanks for sharing. However, if I'm reading this correctly, this project basically recreates an 8088 or 8086 CPU (albeit a faster one). A next step would be to make it function as a 386 upgrade with integrated RAM, unlocking things like protected mode compatibility. Also, the RP2040 is …

How feasible would it be to develop a CPU upgrade board around an RP2040 that would plug into the 8088 or 8086 socket (and perhaps also into the 8087 socket) of a PC/XT machine, and emulate a 386 class CPU, or perhaps even something faster?
