I guess it makes sense. The CPU, Fast RAM and USB I was hoping for could simply be added via the planned 28MHz 68020EC card.
That would just leave the SD/FF on my wish list which is covered by this option:
It will get very expensive though...
You'll need the MB (> 200 EUR) + the (new) scan-doubler card + a (new) IC accelerator card just to build a usable computer.
And if you want to add LAN and USB then you need to purchase further IC cards.
It's great to see a new classic MB of course but this is sounding too expensive.
