A500 power connector modification

[Nosferax]

Hi,

I'm planning to go with an ATX PSU for my new PAL A500 since it doesn't comes with a PSU of its own. But since I can't find any affordable PSU on my side of the ocean (I'm Canadian) to scavenge the 5 pin connector, I'm wondering if someone has ever replaced the female square power jack with a regular 5 pin circular DIN?

That way I coud just buy a 5 pin male DIN connector (really cheap and common) and build myself a cable.

I had a similar situation to yours. Here’s how I solved the problem with a picoitx supply and external 12v power source. I replaced the existing power connector and monochrome jack with a power switch and the lead for the 12v source.



Let me know if I can be any further help.

If its a relatively unexpanded(read not a power hog) a round din will be likely just fine . they are rated for lower amp carrying capacity than the square din(they are rated around what a 500 psu can out out..4.5amps if memory serves).

Instead rebuilding A500 motherboard build own 5 pin square plug - use some 2 components epoxy glue (or buy epoxy resin used by modelers), prepare mold, solder wire to pins and apply epoxy resin. Mold can be made for example from silicone sealant (choose neutral silicone insead those one that smell with vinegar) - silicone is very pro for molds (special silicone can be cheaply bought for this) - i assume for single plug you may think about using polymer clay https://en.wikipedia.org/wiki/Polymer_clay - should be sufficient. Pins can be extracted from cheap DIN connector.

I did build Atari ST floppy cable connector that way, or similar, in the 80's. Another solution could be to us some square hobby plastic tubing and use a thick piece of plastic drilled with 5 holes matching the pins location as the pin support then cap the tubing with that piece. A heat shrink tube could be use to hold the cable coming out of the tubing.

Why that all if new square dins can be bought on lemon64?
