Abstract
The ZX80 computer, fore-runner of the ZX81, could only cope with numbers up to 32 766 and down to minus 32 767. It could not deal with decimals and ignored everything that came after the decimal point. Despite its limitations, it had one or two advantages over the ZX81. It was much faster and it used its memory much more sparingly than the more recent machine. The ZX81 has to pay for its ability to cope with very large numbers and decimals in some way. The payment is made in speed and having to use a lot of memory. This chapter looks at ways of reducing the price we have to pay for the new facilities.
