I made an emulator for some aspects of her machine early on. Not to displace her project, which I thought was great (she's insanely talented), but to bootstrap development of software and demos for when the machine came out. I was on the list to get one of the boards. What she was working on was a far better machine than this 8-bit guy project.

But I pulled myself off the list and stopped working on it when she started making ad hominem personal attacks on me. I don't think she ever liked the emulator project, which is fine, but she made some rather paranoid false accusations against me. So I walked.

It's a shame her project is gone. But there's a similar machine, the Neon816, that is also really interesting.

But after having working with the 65c816 for that period of time I've decided it's a processor I don't really want to play with. It's really unpleasant to code for.

Thanks for providing more information. It’s too bad, but I’m glad there’s a similar project. The true desire to follow the C128 made that a bit more interesting to me than the Neon816, but I’ll give that another look.

One question:

    to play with. It's really unpleasant to code for.

I’d love to hear a bit more. I hate coding for the SNES, but mostly because doing it properly feels like nothing but DMA. What about the 65816 makes it painful in general, if you don’t mind my asking? I find the 6502 very pleasant, if understandably limited.

I've got comments elsewhere in this threat on this topic. Basically, the opcode space wasn't big enough to add new 16-bit addressing modes properly, so they bolted on a 'mode' flag and it's super awkward. It's hacky.
