I have a small question about R34 and R35.

Being 0R I guess they are just links, right?

Do I need to connect both? On the populated Beta board picture here, I can see R35 installed, but not R34.

Yes - I used KM4164 chips originally, although I swapped them out for Phill's modern memory boards afterwards.
Oh, how do I order the tree expansion connector in the middle of the board?
You want these... https://www.aliexpress.com/item/4000215552439.html

For the motherboard it's a straight female. Any expansion cards need right-angled male.

R35 is 0R (or wire link)
R34 is left open.

I'm 22 14-pin sockets away of having all sockets installed... :mrgreen:
Keep going - sorry I've not been looking in enough. Feel free to email me any questions if I don't reply on here, as am keen to see more of these running! ;)
