I started building the Hitachi SH3 core out of personal curiosity. I'm sure you know what I'm trying to build without me having to say it.

Working on a Meanwell LRS-350-12 Adapter so you can use a #molex Minifit JR to Minifit JR cable for the #BC250 PC and have 2 12V taps using JST PH connectors.
Using it in this case: printables.com/model/1714988…
PGM really needs H/V adjustment controls to fit nicely on a regular CRT. I added a horizontal scaler to the core so you can stretch out the image to fit. It works really well! I was surprised that there aren't more visible scaling artifacts.
