The <strong>processor</strong> was essentially the same as that used in earlier Spectrums, but the surrounding hardware was considerably expanded. The machine contained 128K of RAM, arranged ...
... Spectrum and as such have similar capabilities.There are many differences though, the most significant of which is the <strong>processor</strong> used by the Dragon and TRS-80 CoCo, the 6809.The 6809 uses a completely different instruction set and registers to the Z80 used by the Spectrum so any machine code used within a BASIC program will have to be ...
... The hardware The Spectrum+ retained the fundamental hardware architecture of the 48K Spectrum. It used the same Z80A <strong>processor</strong> running 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 ...
