IBM 5110 Keyboard Replacement Test 1
Ғылым және технология
Brief initial test to show concept of applying scan codes directly to the keyboard connector. The scan code for "9" on this system requires just a single pin change, followed by a brief signal on the STROBE pin, making it the easiest key to "type" on the 5110.

If the system locks up, try slightly higher ohm resistors (470, 560, 680).
