CLCT99 and ALCT99 Cards

LCT99 Cards

We built ALCT and CLCT boards that handle high input channel count: 480 strip channels (a whole chamber) and 240 wire channels (one half chamber), as compared to the 48-channel versions used in the '98 test beam. This will verify our plans for crates, connectors, power supplies, etc. We did not implement the full functionality of the RAM-based lookup tables which were used in the 48-channel versions, due to lack of gate array logic blocks.
