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.

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.
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...

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.

Thanks a lot!
I'm 22 14-pin sockets away of having all sockets installed...
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!
