Does anyone have any info on this particular system?
It looks like I've got
Floppy, 2x serial and parallel I/O I think, going by the ICs immediately
around each connector. Just below those appears to be a Z80 CPU, although
how it's used (e.g. simply to control I/O, or to monitor the other
processor cards) I have no idea.
A quick google for Action Computer Enterprise showed a linkedin page and
facebook group, amongst other things, so I'm surprised that there aren't a
few folks around who can answer specifics (and note the "Discovery 500"
system which seems to have built-in drives - so I assume the OP's system is
designed to work with an external drive cabinet).
I'm curious about the large connectors (60-way?) - are those interconnects
to other cards which aren't in the photos, or something else entirely? (I
assume the machine has a solid backplane, i.e. it's not like an RML380Z
where the system bus runs over IDC connectors/cable?)

two different generations of CPU cards for it,
which I was told would not
be compatible with each other. My digging online has turned up very little
on ACE in general.

Pictures of the cards would be helpful. The first card seems to have a ROM
tabled Turbo DOS CPZ 4 8000, floppy only. The card has both a 40 pin
connector and a 26 pin connector (5 1/4 & 8 inch maybe). One of the 16 pin
connectors is labeled plotter and could be a serial port.
