emulatorII-list

Firstly thanks for the advice re: power supply and keys.

The faulty keys are a C, B & yep you guessed it right... the Top C.
If anyone does come across any please shout - otherwise I'll wait for 
Route66 to produce their copies.

With regards to the power supply...  Phillip, are you saying that I 
need to measure the resistance (you mentioned ohms as opposed 
to voltage) between the 0 and 5v wires that come out of the power 
supply, i.e. I get a multimeter and attach one cable to the 0v wire 
and the other to the 5v wire and read off the display ?

Is there a way I can isolate the main board from the power supply and 
see if the disk drives power up ?

If it comes to fitting a PC power unit, is their a standard to these, 
i.e. the yello wire is x volts whereas the red is y volts etc ?

Sorry to seem a bit thick but I'm grateful for your help

Regards
Paul
