I had an empty Franklin mainboard and disk interface card one time some years 
back,  and this is part of the reason why I eventually let it go to some kid 
that wanted to mess with it instead of building it up like I'd originally 
intended.

I remember when I put the BBII together being told,  on the subject of 
interfacing an ASCII keyboard,  that Apple-type keyboards (and clones of 
them) would specifically _not_ work because they set the high bit.  Dunno if 
this hardware you're looking at expects that or if it's even a consideration 
at all,  but figured it would't hurt to mention it.
