It's the same parts except for the pcb. The new pcb makes it much easier and safer to program the xilinx. I suggest, it's worth the couple bucks and couple weeks to get the new pcb.
Also, be advised Steve is getting close to releasing a new REX with the incredible feature that it can let the M100 run CP/M as well as still being everything a normal REX is, for sale not diy. Just in case you hadn't heard. If you only have one machine and only need one rex, maybe that one should be the one. But it's also not out yet, and you already have the stuff, and personally I like building stuff like that, so, whatever just so you know.
