So I just got myself an Amstrad 464 for pennies, it advertised as "dead".
this is what I did -
Questions -
The board is the long board with no "jumpers", is this the version one board?
Is the 40007 fried? where can I get a replacement?
The RAM chips are socketed, are these original or the previous owner has tinkered with the board?
this is what I did -
- connected power supply and nothing, no light nothing.
- opened the 464 up and found that the power switch is covered with "fluff" clean the switch and got the red light.
- removed the 40007(?) just above the RAM chips and founf that one row of the socket was covered with thermal paste. Cleaned the socket and put new heatsink, powered on and still black screen.
- found on the power socket that the three solder points are "dried" will re-solder.
