Since a little fast ram does a lot to speed up wb, it always struck me as strange C= didn't just add two 30-pin simm slots to the A500 or the A1200 designs. It would have been pretty easy to do and Macs of the late 80s/early 90s had them. That way, users could have upgraded their machines to 8mb of addressable fast ram on the m/b easily, kind of like the 4mb simm slots on an Atari 1040STe.
