Okay. This is slightly off-topic, but since the SuperPET[1] -did- have
a 6809 too..
I've recently obtained an old Vectrex, which I want to program myself.
The Vectrex used a 6809 in combination with a 6522 (And yes, that's
about the complete digital assembly, save 1 KB RAM and an EPROM),
and I'm quite unfamiliar with this processor. I do have the
programmers manual (which can be ordered from Motorola - They're shipping
it for free), yet this thing is so different from the 6502 that I'd like
to experiment with it a bit. However, I can't just put in a piece of
code in memory, run it, and see what it has done, due to the way a
Vectrex works[2]. The Vectrex community is sort of spoiled with game
console collectors, so I don't expect much help there. Does anyone of
you know a 6809 emulator somewhere? It doesn't have to be very fancy...
Kind regards,
Martijn.
[1] Which is sadly missing from my collection.
[2] A Vectrex doesn't use a video-image, but has direct access to the
beam deflectors. It draws its own image. You can't hit enter, and
take a peek at some memory locations since there's no way to put
these memory locations on screen easily.
