53	Magnetic tape units 1 and 2
55	DDP-24 FBC
52	CCC input/output (I/O) (3)
49	DDP-24 and DMA
48	DDP-24 FBC
28	Peripheral cabinet, data conversion	Contains portions of the internal DCE. These are SCS hand equipment (DCE) control electronics, which provide hand control inputs to the computer, and the G&N word buffer, which permits computer to interface with PCM-TM encoder (cabinet 30) for G&N 40-bit word.
44	Malfunction insertion unit (MIU)	Contains Computer Control Corporation (CCC) logic cards, relay cards, and associated power supplies. Unit provides for entry of malfunction codes to computer.
41	Digital bit input	Contains CCC logic cards and as so dated power supplies. Unit provides for entry of single-bit switch closures to computer.
47	Analog-to- digital (A/D) converter -	Contains CCC logic cards, associated power supplies, and integrated up-data link (IUDL) - G&tN switching panel, IUDL section provides data tie-in with buffer integrated mission control center (IMCC). The A/D section converts analog information to digital information to be used by computer. G&N buffer provides serial G&N word for telemetry simulation.
43	Digital bit input	Contains CCC logic cards and associated power supplies. Unit provides for entry of single-bit switch closures to computer.
46	Computer interface control box	Contains CCC logic cards and associated power supplies.Unit directs signals between computers and all other units concerned with data conversion.
45	Interface junction box	Contains cabling and connectors, Unit serves as patch panel between data conversion equipment and remainder of simulator.
