Has anyone come accross one of these?

I went to collect a Power Macintosh 5300 from someone earlier, and when I got it home (which resulted in my arms and hands aching alot) and found out that instead of it being a 100MHz 5300, it is actually a Power Macintosh ONE/225, with a 225MHz processor. No wonder it was fast when I first switched it on and started using the installed OS9.1.
