CPC464 version 1 (A and B)

CPC464 Z70100 Tomdalby.jpg
  • Board: PT NO Z70100, without any "MCnnnn" code, Copyright 1983
  • Original version. Big mainboard, old Gate Array (with cooling plate). Real wires going to keyboard.


CPC464 Z70100 MC0001A RobertoCarlos.jpg
  • Board: PT NO Z70100, MC0001A, Copyright 1983


CPC464 270100 Grimware.jpg
  • Board: PT NO 270100, MC0001A, Copyright 1983 (this one is 270100, not Z70100)


CPC464 version 2

CPC464 Z70200 Tomdalby.jpg
  • Board: PT NO Z70200, MC0002D, Copyright 1984
  • Big mainboard, separate soldering points for old and new Gate Array (with changed pin-outs). Fragile plastic wires going to keyboard.


CPC464 version 3 (A and D)

CPC464 Z70374 Grimware.jpg
  • Board: PT NO Z70374, MC0044A
  • Medium sized mainboard. Seems to be same as previous version, except that components are arranged more tightly.


CPC464 Z70375 Tomdalby.jpg
  • Board: PT NO Z70375, MC0044D


CPC464 version 4 (cost-down)

CPC464 MC0099A.jpg
  • Board: PT NO Z80329, MC0099A, Copyright 1988
  • Tiny mainboard. Uses 100pin SMD Gate Array (combines the old Gate Array, CRTC, and some FDC/DRAM/RESET logic in one chip).


CPC664

  • Board: PT NO Z70205, MC0005A
  • 8pin FDC Data Separator

  • Board: PT NO Z7020...?, MC000...?
  • Another 664 version, spotted only a low-quality picture yet... it does exist and does differ from the Z70205 version... but not sure if I have deciphered the board numbers properly... looks like Z70206, MC0005B or so.

CPC6128 version 1

CPC6128 Z70210 Tomdalby.jpg
  • Board: PT NO Z70210
  • 8pin FDC Data Separator


CPC6128 version 2

  • Board: PT NO Z70250
  • Not sure if this version exists, maybe somebody just misread or mistyped the Z70290 board number (?)


CPC6128 version 3

CPC6128 Z70290 Yarek.jpg
  • Board: PT NO Z70290, MC0020B, R1706-94HB, Copyright 1985
  • Can be fitted with Amphenol connectors (done in germany) (instead Edge connectors). Uses 24pin FDC Data Separator.


CPC6128 MC00201 RobertoCarlos.jpg
  • Board: PT NO Z70290, MC00201, 94V.0-FR-4, Copyright 1985


NoPicture.gif
  • Board: PT NO Z70290, MC0023D, 94HB-R1706, Copyright 1985
  • Sold in germany (with Amphenol connectors, and dummy edge-connectors which covered by green solder-stop layer, front of mainboard has several vias for giving better contact to shielding plate).


NoPicture.gif
  • Board: PT NO Z70290, MC...?, 94...?
  • Looks almost like the above german board, but the "94HB-R1706" is different
  • weblink (not very good picture quality; and board numbers are hidden under shielding plate and capacitors)


CPC6128 version 4 (cost-down)

CPC6128 Z80330 Yarek.jpg
  • Board: PT NO Z80330 (1988)
  • Uses 100pin SMD Gate Array (combines the old Gate Array and PAL, CRTC, and some FDC/DRAM/RESET logic in one chip).
  • Can be fitted with four 64Kx4 RAM chips (or the normal sixteen 64Kx1 RAM chips)
  • Printer port consists of 74LS174+74LS175 (instead of 74LS273)


CPC 464+/6128+

CPC464Plus MC0122D NightfallCrew.jpg
  • Board: 2700-016P-3, MC0122D, Copyright 1990
  • Same mainboard is used in 464+ and 664+ (though not all components installed in 464+, and with different LK Links. Uses 160pin SMD Gate Array (ASIC).


GX4000

GX4000 PCB Top.jpg
  • Board: 2700-017P-4, MC0123C, Copyright 1990
  • Same chipset as CPC+, but lacks Keyboard, Expansion Port, Printer Port, Tape/Disc Interfaces.
  • Additional Scart Connector and TV Modulator (the modulator isn't installed in all versions, and IC101 may be replaced by 4 transistors, as seen on this other picture).


DDI-1

  • Board: MF0004B, ISS3
  • 20pin FDC Data Separator
