MiniPET Replacement: Part 2 (Installed in the PET)
9Finally got my PET back from the powder coaters.
For AU$230 (plus 10% GST) they sand blasted, primed and re-powder coated the main three parts: bottom case (satin black), top case and monitor (evening haze).
I've taken copious video of the disassembly (lots of rivets to remove) and reassembly, but I thought this "quick" video showing the finished product might be of interest. There's still a display fault I need to fix before it's complete (shown at the end).
The original 100V Japanese transformer has been removed and a 12V/6A switching PSU installed in its place, which cost me only AU$20.
The 12V supplies both the MiniPET board (which has on-board regulators) and the CRT (which takes 12VDC).
The MiniPET requires 6V (for the Datasette), 5V (for the logic) and 3.3V (for the SD card).
As it's a Japanese PET there were some holes drilled into the front of the case to select the original ROMs - I've re-used these holes for the SD menu select and the reset switches.
My 3032 is now running BASIC 4.1 in 40 or 80 columns.
12V power supply:
Mean Well LRS-75-12RCM
