No...I did mean C6 (3-pin) since Jim mentioned asking PSU builders
about the C13 (C14 inlet). If the PSU doesn't require an earth/ground
terminal though, the C8 would probably be a better choice since it
would be less expensive to implement than either a C14 or C6 inlet,
and take up less space. The only other reason I could see for using
the C14 over the C8 or C6 is that the C14 is good for up to 10A,
whereas the C8 and C6 are rated for 2.5A, but I really can't see a C64
PSU needing more than 2.5A at mains voltage. If you are open to considering either a C5 or C7
IEC 60320 coupler
instead of the C13, you'll probably have better luck with the PSU
vendors. If you don't need the ground/earth terminal (I can't see
why it would be needed for a replacement C64 PSU) a C7 will also cut
the per unit cost and allow for a smaller case.
I don't think you mean C5 (or C6). That's a 3-pin, the one sometimes
called "mickey mouse ears", and one of the less-common types. I
mostly see it on Toshiba laptop power supplies.
C7 (cord connector) and C8 (inlet) is 2-pin. It's the one often
referred to as "figure of eight", and the only common 2-pin.
The C5/C6 is now very very common with newer laptops and IT equipment.
In the US, the C7P polarized version is extremely common with consumer
home audio equipment. Both the C1 and a coupler similar to the C1 that
is more rectangular with rounded corners (still 6.6mm c-c) vs the more
oval version in the standards are also very common with battery
powered portable radios and similar that also have an internal power
supply. The 'rectangular C1' cords that I have on hand are made with
18 AWG SPT-1 cord and have 125V 7A molded into the coupler body.
Besides
potentially, Delta, though, I'm not having much luck with any
type of connector.
Sigh.
