Dual MALU• 32 inputs, NIM or TTL (selectable at eachinput)• Two logical groups consisting of userprogrammable subset of the 32 inputs• In each group:

• Delay gate generators at each input(100 MHz)• Four outputs

• 3 of them just discriminators withprogrammable thresholds• one implemented as pattern checker

• Counters at each input and output fordebugging
