Summary: I had the case re-powder coated, put a new label on, installed a new switching PSU and a MiniPET 4080D. I still have an issue with the CRT that I need to fix, and need to get new rubber feet.

As you will see from the date stamps this was filmed over a few years - just finally got around to putting it together.

The powder coating was done locally in Port Macquarie and cost me AU$230 (plus 10% GST): they sand blasted, primed and re-powder coated the main three parts. The bottom case used "satin black" and the top case and monitor used "evening haze". I would say it was worth doing.

I decided to get @DaveCurran's (Tynemouth Software) replacement PET board (MiniPET 4080D) as this would give me a lot of different PET options to play with, including 80 columns, as well as greatly simplifying the power supply:

We use 240VAC here in Australia so the original 100VAC transformer had to be replaced.

I opted for a modern 12V/6A switching power supply (Mean Well LRS-75-12RCM) which ended up only costing me AU$20 (on sale at Jaycar). This supplies 12VDC for the CRT and the MiniPET 4080D board, which converts this down to 6V (for the Datasette), 5V (for the logic) and 3.3V (for the SD card).

I couldn't save the original label so got a replacement:

The top case was riveted to the bottom case via a hinge - I simply used M3 bolts/washers/nuts when re-assembling.

The bottom case also had holes for switching character sets - I re-used these holes for a reset switch and SD menu trigger.
