I found Brent Hilpert’s site most useful in getting a quick meaning for these numbers: http://madrona.ca/e/HP21xx/index.html http://madrona.ca/e/HP21xx/iointerfaces.html There is also a very useful series 1000 reference manual that lists most of the configs and options and cards, I will get to it when I am home and try to send you a link.
My experience is that you absolutely have to open them up to figure out what they actually are. They are so modular and upgradable and interchangeable that the original config sticker rarely matches what’s inside. Actually, I have yet to see one that has a config that matches the factory sticker. Sometimes the motherboard isn’t even the series that the front panel says! Also you need to find out what optional microcode ROMs they are fitted with (extended/virtual memory, fast fortran, vector, scientific, etc...) to know what version of RTE they can actually run, and which boot ROMs are installed. That said they are very easy to take apart, just open front and back, slide out top and bottom covers, slide the cards out, and admire the modular design. They are also very well documented.
