-Chapter 18 of the BASIC manual supplied with the ZX Spectrum includes two programs to implement of a clock - each uses different timing methods. The first - using a PAUSE command to hold for a second - is far less accurate, while the second - reading the three-byte system frames counter - is more CPU hungry (since ZX Spectrum Basic can't multitask, this doesn't really matter). With a tweak, the second is shown below.
