About this model

This will allow you to completely replace the PSU in an Acorn Archimedes A3xx or A4xx/1 series machine using a Meanwell PT-65A power supply. You'll need to either adapt your existing wiring loom, or build a new wiring loom, remembering to connect your case to Earth using a ring and one of the screw positions on the case. To print supports in the right place, and not fill all the holes with supports I set the support overhang to 80%. You can get a grommet for the cable hole from Amazon: The screws are all 3mm self tappers.
