Subject: Apple Z80 hardware

If the board has some DRAM, it's the ALR Z80 card. If no ram
of its own, it may be a clone of the Microsoft Z80 card. These
each require their own boot disks, but data disks are compatible
between the two systems. The ALR card supported some add-on cards
for extra memory , maybe even a version of CP/M Plus.
