360 - I think I have only one board, in my TEMPEST, that has that tiny jumper board on the SE.
Elfen - I think there are more platinum Pluses out there than most think. if you looked at my pile, maybe one looks like a platinum but the rest look beige. Only looking at the serial label reveals there are two more. So I think the yellowing seems to skew the counts. I could be wrong, but thats my guess. I too thought (due to lore apparently) that the Platinums were harder to find. As for the squirrel cage fans, machines with those are not too common. I have a two I think, maybe more since I dont look at the fans to closely. They were so loud that Apple had a replacement program for them. Which I think is why they are less common - shorter production time, "recall" of sorts. But dont think any SE/30 came with one unless the power supply was replaced with one. I guess in a way, for the hardcore collectors, I should add a note about the fan. It was a version I myself looked for after all.
James - I made note of the "P" for 220-240v supplies below the 128k/512k models above in the list. As far as I know, once the "e" of the 512k came out they did not use the "P" to denote power supplies anymore. I could be wrong. I just have never seen a model like M0001EP or M0001AP, etc. I could put them into the list proper, but that would add a few lines for sure! As for the one you just acquired, compare the serial on the front with the model number on the back with the regulatory label. They should match. If not then its a regular Macintosh that was upgraded. Official Apple upgrades came with new regulatory labels and badges. But they were not always installed.
