The MAC-16 in this ad looks odd. The front panel has nothing behind
it...or at least, very little. I'm not familiar with the MAC-16, but
either the ad has a mock-up of the machine(seems plausible given the
tendencies of marketing), or the front panel is a real waste of rack
space. The electronics appear to be in a box below the front panel,
with only a small area of overlap between the electronics chassis and
the front panel, and nothing but air behind it.
Is this the way the system was really put together?
