about this before, but I have no FPGA experience at all, and wouldn't
know how to start. If it's just a matter of taking a a core model,
setting it up for the target device (assign pins etc.), and writing it,
I'm sure I could cope with that. But I suspect I'm simplifying things
greatly there. It'd also depend on whether a 6809 model would make it
obvious how to get at the LIC and TSC signals. Maybe there's someone on
this list who I can pester with questions?
It is seldom that easy, but it can be made to work. You could even
potentially spin your own drop-in replacement board. You're welcome
to pester me with questions, though ideally off-list because I think
everyone here has heard all the "FPGA replacement for <device>"
conversations they want to. :-)
