ID-4804 Byte Probe

The Heathkit ID-4804 Byte Probe is a unique test
instrument for checking +5 VDC logic states of address
lines in either TTL or CMOS circuitry.  The Byte Probe
contains eight switch-selectable input channels which 
can be selected to detect a logic level of “1” (high),
“0” (low), or “X” (don’t care). A “time” switch allows
selection of one of three display modes: real time, pulse,
or latch.
