(b) Not only do I have the original but I have three spare ones, including a spiffing ceramic and gold one.

Can't argue with that logic.

I dont really follow the Atari stuff here, so my knowledge of this project is pretty much zero, but it seems popular and that has peaked my interest :) First and foremost it's worth pointing out that this is a "build it yourself" project, save for the SMT passives that will come preattached, so if ...

And yet more... use @derkom 's relocator design to also have the 68000 on the board so that you can switch between that and the TF536. You might want to ponder using a PLCC 68k for this, depending on how tight space gets. On my Stacy switcher, I had to use the DIP 68K because of needing to fit the ...

What amazes me things like this is that someone has produced these, the molds, the tooling and run off a load, which means there research lead them to the answer there's a worthwhile demand for it

LOL! Awesome!

And there you have it.

Since this design works well at this point, and may be of some use for someone else, here's the KiCad files for the switcher board. The PCB layout itself is very specific to my build, but the electrical layout for the muxes should transition fine to any similar switching setup. A couple of things to...

That and I liked @derkom's idea to keep both CPUs inside the case to switch between them. Since the design seems to work well at this point, I'll stick the KiCad files in my thread. The physical PCB is obviously Stacy-specific, but the electrical layout should transfer fine to any similar projects....

Uwe is somewhat difficult to deal with... PP isn't exactly easy to deal with either.

In my lengthy experience in the field, I've found that rarely do refined social skills and a deep understanding of SCSI arise in the same person. But we are definitely glad to have those guys when we need them.

That read like a thriller novel

It was supposed to.

Ran into a pretty strange problem today. I'd noticed yesterday that I wasn't getting a reliable boot, but the system did boot when I moved the floppy drive out of the way, so I figured one of the feet on the drive cage must have been misaligned and was shorting something to ground. Cue my disappoint...

Yes, save the confusion for the building.

I'll be sure to order another gallon of flux.
