A training aid developed to help teach basic principles of process control and computers. Contains LS TLL CMOS compatible integrated circuits. Molded plastic ABS case. Soldered connections are easily replaced. Training systems offers versatility, reliability and durability. Symbols allow for easy identification. Includes lab manual with answers.

The CL-SLD includes the following components:

• Basic SLD i-34 module (mounting board, function generator, power supplies, displays and switches).
• SLD i-35 combined circuit module (NOT-AND, AND NOT-OR, OR, and OR ONLY gates).
• SLD i-36 sequential circuits (J-K, D, R-S switches, Schmitt trigger gates, timing log, decade and binary counters).
