Amstrad CPC 464 Plus (Keyboard problems are Fixed)

Amstrad CPC 464 Plus

Autopsy:

from Wikipedia:

The Amstrad CPC is a series of 8 bit home computers produced by Amstrad during the 1980s and early 1990s. “CPC” stands for ‘Colour Personal Computer’, although it was possible to purchase a CPC with a green screen (GT64/65) as well as with the standard colour screen (CTM640/644).

In 1990 Amstrad introduced the “Plus” series, 464 and 6128 Plus, which tweaked the hardware and added a cartridge slot to the system. Improvements were made to the video display which saw an increase in palette to 4096 colours and gained a capacity for hardware sprites.

Splitting the display into separate modes and pixel scrolling both became fully supported hardware features. The former was reasonably easy on the non-”Plus” machines, and the latter possible to some degree using clever programming of the existing Motorola 6845.

    I hope it is as easy as that to repair the CPC 6128+ keyboard I just bought.

    The “2″ key doesn’t work so I cannot load anything :(

    If you find your disk drive does not work, it is highly likely that it is a problem with the rubber belt which connects the motor to the spindle. It is a cheap an easy fix, you can get them from http://www.thesinclairshop.com/

    In case anyone else finds themselves with one of these without a monitor, you can power one with a REGULATED, 5V, 2400mA, AC-DC transformer. Needs a 2.5mm jack, centre positive. (lad6019a55 about £7 on eBay). The CPC6128+ does NOT need 12V which makes the PSU’s cheaper.

    Also it is very easy to make a SCART cable (8-pin DIN, SCART plug, 7 core cable)

    @kirst

    Yes, the rubber pulley is dirty or consumed or the capstain is crooked.

    search “capstain tape” on google.
