I'm lucky to own one of these since a day.
But I am having the idea that internal power doesn't cut it, so I want to make a power supply, the manual lists it as this.

13.3.4 External Power Supply
Pin Signal
1 GND
2 GND
3 +5VDC
4 NC
5 +12VDC

Only problem is that it doesn't mention which pin is on what side, so how is it ?
Left to right 1-5 or right to left 1-5 ?

If you are using a 3.5" HD then an external PSU is probably best, but a CF card or possibly a 2.5" HD should be fine drawing power fom the A500. I'm sorry i can't help you with the pin numbers.

Just out of curiosity, what is the capacity of your drive? and is your Alfapower the one that uses ZIP memory or simms? I'm having loads of issues getting mine to fully work with my A500+ :roll:

It works fine, it has a full row of 8MB zip ram and has a 3,5" 3GB and now a 40GB is prepping, also CDROM attached.
I will move to CF a.s.a.p.
Will take out the CF in one of my A4000's and dump a 250GB IDE in it.

So you have the older model like me with ZIP RAM (i also have the full 8mb :)). I guess your one must have a different/updated ROM as i've been struggling just to get a 2gb CF card to work!

I tried a simple PCs keyboard's connector and fitted perfectly !!!

So we' ve got the connector we need the pin numbers.

According to "google" the PC keyboard's connector is like that
