Photos of BayCom USCC>4



This photo shows an assembled USCC>4 without modems:
The two 40pin chips are the communications controller Z8530, the chip with the white label is the GAL used for address decoding. The slot connectors for the four piggyback modems can be seen clearly.



The next photo shows the same card with three piggy-back modems inserted. The modem most right (channel 0) is the TCM3105 modem, the next is an AM7911- Modem and the modem on channel 2 is an SMD DF9IC-modem. Channel 3 carries no modem. The total hight of the assembly is about 18mm, so the card does not block the neighbour slot.
