those are cards from an ACER 500 XT system IIRC, I had one at some point
the bottom one is the cpu card and the top one is the cga/fdd/serial/parallel card
both connect to an isa backplane
if I find my old pics I will post them

my thread about the system is here: Acer 500+ XT system but sadly pics are no longer working for the first couple of pages

2nd card is a MFM HDD controller

The 3rd board looks like to be from a Olivetti M24

EDIT: Nevermind. It looks like it has a NEC V40 CPU, so it can't be a M24 motherboard, as the M24 used a 8086.
