Hello All --

I'm the proud (?) owner of some surplus Z80 boards that look like they
have connectors for the Apple bus on them.  There was no documentation
available, and I'm wondering if any of you Apple CP/Mers might be able
to help identify them.  They are marked "Advanced Logic Systems".  There
is a "Z80 Card" that is a Z80B and little else but some interface chips
and a small PROM/ROM(?).  It does not even have an on-board clock that I
can see.  Also I have a "CP/M Card" from the same vendor.  It is unpopulated,
but looks like it would have memory, a crystal, etc.  There are no component
values or IC id's on the silk screen.  Can somebody tell me if they are
useful, or if there is documentation available for them??
