Sorry if this is an obvious question - about to order the IC's, I dont see them mentioned on the bom XLS files? Is it just the same ICs used with the 536?
No, you need the XC95144XL CPLD (the same one used on the TF330).

Thanks, what about RAM and the other chips on there (buffers)? Is there a specific speed of that CPLD required?

The buffers & RAM are the same as the 536, and the CPLD speed is the usual 10ns.

Thanks! Ordered from Mouser - CPLD wont be here until October - best of a bad situation really. Couldnt find the parts in stock across all the suppliers I tried. This chip shortage thing is getting worse it seems...

Btw Thank you @go0se for supplying me with nice kit. Sourcing parts (including proper 50Mhz 030! - first I ever seen) would take me ages.
Ps
Pay attention to to buffer orientation, unless you want to have nicely toasted finger.

Yes! Everything is starting to get out of stock, even the most basic parts. It's very annoying.

Ordered my parts straight off the 1230 Schematic file in Eagle that file is showing a XC95288XL as the CPLD

Is that a hassle producing a different jed :?: If so, no problem will simply put the build on hold, and order a XC95144XL
