- After 6 months I `ve finished it. I used a 1/4 watt 270 ohm resistor instead of 1/2 watt on the R60 resistor Mod. and sent 22 volts onto the 12 volt rail. New lower Ram, upper Ram, T4, T5, caps, diodes, keyboard membrane, 5 volt regulator, power socket, video mod and home made ULA heatsink.
all working now then mate where you getting the speccies from i know one you had years ago but have you got more than one now double sided sticky tape blue peter special mate :)
My first computer was this Speccy model. So I wanted one again. I get them off EBay. About £50 each. I might try Torksey Car Boot soon.
@@damianbutterworth2434 next need to find a way to network them lol
Just watching your video, if your ULA is too hot to touch, may I suggest that it's nearing death. You don't need an extra heatsink. The tracopower negates the need for the native one.
Good luck.
@@StuHo1mez I should get a modern ULA for it. I`ll keep an eye on it. Perhaps I killed it with the over voltage. To be honest it was real hard to get the picture set up with this ULA. I fitted another and the screen was perfect. Thanks for the advice.
