[GreenKeys] SB-1203A Patch Panel (Manual wanted)

[Gregory W. Moore]

If anyone has a manual for the SB-1203A patch panel (6 loops), I would
like to buy same, or will trade for a copy of a manual for SB-2244/UG
patch panel (3 loops/3 stepping loops). I recently obtained a SB-1203
for my shack, but the manual was for the other unit.
For info, the SB-1203A was used as a "black" panel (unclassified or
encrypted data) while the SB-2244 was used as a "red" panel (secure,
input to crypto devices or output).
