... be the stack’s top value. The machine code routine removes all values from the stack and should be terminated by a <strong>Z80</strong> ‘RET’ instruction. CHANGE_ CHANGE_m,nResult : Changes attributes, the mask (m) is negated with each attribute byte; the data (n) is then ORed with each attribute byte. See also FADE_, INVERT, SWAP_. CLW_ ...
... command appears to exist for the Atom. OUT OUT m,n (ZX Spectrum)Result: Outputs byte n to port m.Note: Executes the <strong>Z80</strong>A instruction OUT (c),a. The Atom utilises the 8255 Programmable Peripheral Interface Adapter for input and output. Port A is location #B000, Port B is location #B001, and Port C is location #B002. See also: IN. OVER ...

... the machine was being used in its new 128K environment. Hardware At the heart of the ZX Spectrum+ 128K was a Zilog <strong>Z80</strong>A processor running 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, ...
... incorporated a built-in cassette recorder, making it a much more complete home-computer system. The +2 retained the <strong>Z80</strong> processor and the basic architecture of the 128K Spectrum, including its 128K of RAM and AY-3-8912 sound chip, while replacing the separate external cassette recorder with an integrated unit. The new case also ...
