PET 2001/3008/8032

  • 2001 series released 1977

  • 3008 series released 1979

  • CPU 6502 at 1MHz

  • RAM 8k (expandable to 32k)

  • ROM 20k - Microsoft BASIC + "TIM" monitor

  • Text 40x25 (black & white)

  • Integral 9" monitor (12" on the 8000 series)

  • Tape and 5.25" floppy discs

  • Parallel and IEEE-488 bus for peripherals

The PET series were aimed at business use. The 2001 PET had an integral cassette tape and a reduced size keyboard, and an annoying flicker every time the screen scrolled. Most peripherals, eg printers and disc drives (which were huge! Nearly as big as the PET itself), were daisy chained to the IEEE-488 bus. Additional hardware expansion included a high resolution (320x200 black & white) graphics board.


C64

  • Released 1982

  • CPU 6510 at 0.9MHz

  • RAM 64k

  • ROM 24k

  • Text 40x25 (16 colours)

  • Graphics 320x200 (2 colours), 160x200 (4 colours), hardware sprites

  • 3 channel sound (SID)

  • Tape and 5.25" floppy discs

An extremely popular home computer with excellent software support. It came with Commodore Basic V2 (unchanged from the PET), which had no support for the graphics or sound. The disc interface was compatible with the VIC20, and extremely slow. Some of the games company's custom tape routines were faster! The cartrige port was used for programs and additional hardware, including a sound sampler and an FM sound box with music keyboard.


610/620

  • Released 1983

  • CPU 6509 at 2MHz

  • RAM 128k (610)/256k (620)

  • ROM 24k

  • Display 80x25 (16 colours)

  • 3 channel sound (SID)

  • Tape and floppy discs

  • IEEE-488 bus for peripherals

A cross between the PET and the C64, these machines were not very successful and not sold for very long.


Plus 4

  • Released 1984

  • CPU 7501 at 1.75MHz

  • RAM 64k

  • ROM 32k

  • Text 40x25 (16 colours)

  • Graphics 320x200 (2 colours), 160x200 (4 colours), 121 colour palette

  • 2 channel sound

  • Tape storage

    Not a popular machine, although in some ways more powerful than the C64 (with Basic 3.5 and an increased colour palette), most people bought the C64 because of its good software base.


    C16

  • Released 1984

  • CPU 7501 at 1.75MHz

  • RAM 16k

  • ROM 32k

  • Text 40x25 (16 colours)

  • Graphics 320x200 (2 colours), 160x200 (4 colours), 121 colour palette

  • 2 channel sound

  • Tape storage

    Not a popular machine, although in some ways more powerful than the C64 (with Basic 3.5 and an increased colour palette), most people bought the C64 because of its good software base.


Amiga A500

  • Released 1986

  • CPU 68000 at 7.44MHz

  • RAM 512k

  • ROM 192k

  • Text 80x25

  • Graphics up to 640x512, palette of 4096 colours

  • 4 channel stereo sound

  • Integral 3.5" floppy disc

    Very popular and powerful machine. The graphics and sound were arcade quality and many of the games which were produced were very addictive.


Amiga A600

  • Released 1992
  • CPU 68000 at 7.44MHz
  • RAM 512k
  • ROM 192k
  • Text 80x25
  • Graphics up to 640x512, palette of 4096 colours
  • 4 channel stereo sound
  • Integral 3.5" floppy disc

    A cheaper version of the A500.
