Revision as of 08:21, 9 April 2010
Contents
CPC464 version 1 (original)
- 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.
- Board: PT NO Z70100, MC0001A, Copyright 1983
- Keyboard connector now has two rows of soldering points (maybe intended to allow to use different connectors)
- Board: PT NO 270100, MC0001A, Copyright 1983
- This one is labelled 270100, not Z70100.
CPC464 version 2
- Board: PT NO Z70200, MC0002D, Copyright 1984
- Separate soldering points for old and new Gate Array (with changed pin-outs).
- Fragile plastic wires going to keyboard.
CPC464 version 3 (medium-sized)
- Board: PT NO Z70374, MC0044A
- Medium sized mainboard. Seems to be same as previous version, except that components are arranged more tightly.
- Board: PT NO Z70375, MC0044D
CPC464 version 4 (cost-down)
- 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.
- http://amstrad.cpc.free.fr/amstrad/cpc664_e.htm
CPC6128 version 1
- 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
- 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.
- Board: PT NO Z70290, MC00201, 94V.0-FR-4, Copyright 1985
- 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).
- 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)
- 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+
- 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).
6128+
- Board: 2700-016P-3, MC0122D, Copyright 1990
- Same mainboard is used in 464+, but with additional components installed (extra RAM chips, FDC chips, Floppy connector, and with different LK Links).
- Uses 160pin SMD Gate Array (ASIC).
GX4000
- 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).
- Board: 27...?, MC...?, Copyright 1990
- Version without TV Modulator installed, and IC101 may be replaced by 4 transistors.
- See this picture (might be same mainboard as above, not sure - the photo doesn't show the boards part number; hidden behind the cartridge slot, one thing that IS different is the K1 vs K3 text near the LED).
DDI-1
- Board: MF0004B, ISS3
- 20pin FDC Data Separator
- Photo of the above Board: MF0004B, ISS3 (and maybe other ISSues, if any?)
