Summary
| Description |
This is an IBM SMS card post 1969 even though the card format had changed with the System/360. The NPN transistors are date code 1970 but are IBM 030 and 044 transistor models defined in the late 1950s. The IBM module (on the right) is early SLT (Solid Logic Technology). The card is from a 2420 tape reader. Tape machines and other peripherals kept the SMS format and the component technology longer. |
