VCF 1130 system is missing two SLT cards to support the full complement of configured peripherals

TWO 0000 SLT CARDS ARE MISSING FROM THE MACHINE

These are the most common of SLT cards, providing four double input "AND" gates and two triple input "AND" gates. These are in fact NAND gates, as the output goes low only when all the inputs are high, but IBM either calls them A gates or alternative OR gates (with the output high when any input is low). Exact same truth table, which the rest of the world would call a NAND. 

NOT A PRACTICAL LIMITATION FOR THE VCF MUSEUM

The museum owns an 1132 printer and a 2501 card reader, but not a 1442 reader/punch. Thus, there are spare cards from the 1442 controller logic that will complete the machine for the peripherals it will be attached to during its use at the museum.
