|Left: This was a basic studio, event timer
clock. The display and some logic
functions had seen better days. So I
decided that this beautiful hardware
needed a new set of guts. Hat tip to Carl
for the gift.
The chassis and panel are first class
materials and construction - by "System
Most of the innards will be removed, since
the new clock module requires cmos
supply levels with some TTL thrown in.
Mechanical switched logic will be replaced
with ROM logic firmware and the display
will be a rear illuminated LCD board.
I decided to add some of the display
features that we were used to in the Air
Defense Command (Army) with some of
the excellent Signal Corps equipment.
The readout will be selectable for;
Night Vision (red)
Room Light (blue)
High Visibility (white)
|The switched circuits will be;
120 VAC N/O
12 VDC N/O
Dry Contact, Sinking (N/O), 10 Amps
|The final result of the revised Studio
The finished clock
The four basic display
Room Light Vision
High visibility, pale
green, aqua, pink, etc.
