cool ok the core is controlled by the ISL6522CR

I'll sort out the vmods very shortly but it looks like you wanna look around pin 3 and measure the resistence to ground from that pin ;)

[Dualist]

Measured between pin 3 and pin 6 (ground) and got 500 ohms. :)

[Johnny Bravo]

ok try a 5 or 10Kohm resistor soldered between a suitable point directly attached to pin 3 and ground, and slowly decrease the resistance to see if we're on the money :)

Have you found the necessary voltage readout points?

[Dualist]

Ta Johnny, will test when I get back home at the weekend.

Have you found the necessary voltage readout points?
No, I'm shite at electronics :D

I'm thinking upper right hand corner cap marked "1500" will be vgpu and lower right cap marked "1200" for memory. positive side is the side NOT marked with a blue/black line

Tho I could be totally wrong, so measure them all and report back :D

At the 1500 point I get 1.64volts.
At the 1200 point I get 1.19volts.
Before any mods :)
