| Basically "IN" | An advantage of using the IN function instead of INKEY$ is that multiple keys can be sensed. If the keyboard was to be divided into 8 groups so that each group was half a row containing 5 keys, then these groups would be represented by IN addresses as follows: When IN 65278 equals 31 (binary 11111), none of the keys From CAPSHIFT to V are being pressed. | Timex/Sinclair 2068, Type-in program |
| Bob's Notebook: Binary Search | This is program is based on one by John Gilbert published in Timex Sinclair User VoL. 1 #4. Compared to the slower serial search often used in BASIC programs, the binary method is quite fast, doing its job in about one tenth of the time. | Timex/Sinclair 2068, Type-in program |
| Clocking the 2068 | Our 2068’s have a built-in clock, sometimes called the Frame counter. This clock starts at zero every time the computer is turned on. It increments the value at the variable address 23672 every 1/60th of a second until it reaches 255. | Timex/Sinclair 2068, Type-in program |
