Sometimes, this list is weird.

I was wondering about it too, and waiting for you to come up ;-)

Anyway, I hope you don't mind if I post the links to two pictures which 
hopefully show how it could work:

a.) the cpu board http://n8vem-sbc.pbworks.com/f/IMG_5762.jpg
b.) the fdc http://n8vem-sbc.pbworks.com/f/IMG_8632.JPG

So, if you use a right angled power-connector on the cpu, you could 
probably just stack those two board on top of each other, without the 
need of the bus backplane.

My thoughts to all of this:

1.) I don't care about the sd-flash, Not sure if it really helps. After 
all, we still talk about floppies, so a decent V24 should be good enough 
to send /receive data from a floppy.

2.) The board is missing the 8" floppy connector, which is bad. Would 
make it easier to get the people playing with it. I know, you can wire 
it up easily, but you probably like to get the software people on board 
too ?
;-)

Cheers

BUT I'M WATCHING IT FOR A WHILE. LIKED TO PLAY WITH CP/M AND Z80 BEFORE)
