I'm still gathering components and hope to start building mine soon.

I had to move to a new a couple of months ago and hadn't time to put myself into it.

Excellent work John. What's the best way of building this? Use a broken donor Dragon or buy all individual components? Does the board fit the Dragon case or is this totally different?

It's a completely different beast. You'll need to research it, and it will cost you a lot to make it.

No, but you can generate one from the KiCad schematic.

I'm half way through the Beta board soldering, and would like to know if I can use 4164 ram chips instead of the MK4564N ones.

Other than that, I have almost everything I need including the 93L422A chips.

Oh, how do I order the tree expansion connector in the middle of the board?

Looking good Rob!

I think the two DRAM types are nearly equivalent, or at least I'm sure I've had both types in my Dragons.

I found this handy reference the other day. Might be of use: https://minuszerodegrees.net/memory/4164.htm

Those 3 connectors look like DIN41612 type B 64 way to me, probably sockets, but you'll need to double-check to be sure.

Thanks a lot!

I'm 22 14-pin sockets away of having all sockets installed... :mrgreen:
