Manual Entry Keypad Assembled

Slowly moving along on WITCH-E... new PCBs arrived today...

The original WITCH has a manual input panel in order to input commands. this is manual for testing and selecting control of which tape readers to start executing from. For WITCH-E it is an intermediate step between having the tape readers working and being able to fully test the system... next board to be assembled is the keypad encoder which will take the keypad input and cover it to a 5-bit baudot like encoding...
