Parts Questions

I am building the powersuply for my sid using an old c64 power psu.  On the diagram for doing this it says that you can connect the power led from the C64, i havent got one, any alternitves?

any led will work…there’s nothing special about the c64 led.  if you’re using a display with a backlight, you don’t even need an led, because the screen itself can act as your power indicator.  if the screen is lit up, the unit is on.

ok cos on tk’s diagram http://www.ucapps.de/mbhp/mbhp_4xsid_c64_psu_optimized.pdf

the conection for the led has 3 pins why is this?

i thought perhaps the c64 led had 3 parts for the 5v and the 9v

i think he just did it that way because the C64 led has a 3-pin socket at the end, even though only 2 of the pins are actually connected to anything.  you can see in the diagram that the third pin is connected to the first. i think this is done for orientation reasons; no matter how you connect the socket, the C64’s power led is going to function properly.  the led itself, however, only has two leads…it’s just a normal led.

let me know if this is unclear.
