Any model of any console motherboard can be trimmed, but the community chooses to target specific motherboards since they are often the most optimal for portablizing. Sometimes this is because is because they draw less power, other times this is because they're much easier to trim down to a small size. In the case of the PS2, we use the 7900X models since those have the most optimal motherboard for our purposes. Odds are, if there isn't a trimming guide on the forums here for the 75001 model, then there probably also isn't a trimming guide for it anywhere else on the internet.
