... was being used in its new 128K environment. Hardware At the heart of the ZX Spectrum+ 128K was a Zilog Z80A processor <strong>running</strong> at approximately 3.55 MHz. The processor was essentially the same as that used in earlier Spectrums, but the surrounding hardware was considerably expanded. The machine contained 128K of RAM, arranged as eight ...
... instead it uses integer based arithmetic. This can make complex mathematics like trigonomety a bit tricky. Programs <strong>running</strong> under integer based BASIC may run faster than those <strong>running</strong> under floating-point BASIC, so the ZX80 may actually run some programs faster than the ZX Spectrum.On the ZX Spectrum and ZX81 a single keyword entry ...

... RUN a program from line m once loaded. On the ZX81 the same is achieved by inserting a SAVE command into a program and <strong>running</strong> the program from the line number where the SAVE statement is. The last letter of the filename will 'invert' and when loaded back the program will run from the line after the SAVE statement. The ZX Spectrum will ...
... The Spectrum+ retained the fundamental hardware architecture of the 48K Spectrum. It used the same Z80A processor <strong>running</strong> at approximately 3.5 MHz, 48K of RAM and 16K of ROM containing the Spectrum's BASIC and operating routines. The display system remained the familiar 256 × 192 pixel colour display with the Spectrum's eight ...

The +3 therefore represented something of a crossroads for the Spectrum. It retained the identity and compatibility that had made the machine successful while attempting to ...
