@Lorraine:
I don't think so. It is supported by SAGE, but nobody supports SAGE :-)
@coldfish:
I personally didn't really want it (unless it came with full programmer's documentation or at least the register set documentation), but I just wanted to "test the waters".
You're absolutely correct about classic cars vs classic computer gear. Cars haven't "advanced" so much in the last 50 years, so that a car that's new can do a whole lot more. They both do the same (take you from point A to point B) and more or less with the same success (ok, so the newer ones have heated seats! ;-)). But I mean, the new ones don't fly or warp space and time.
New computers on the other hand have advanced so much that the old ones do feel obsolete when it comes to "heavy lifting". They're not worthless, nor junk, but don't quite compete. The differential is exponential.
Of the old classics, only a souped up Amiga can come close to today's powerhouses :-)
