Big dollars paid for Altair 8800 on Ebay

A confession. I'm not a collector. I don't understand collectors, particularly the exhaustive ones. You see this sort of thing a lot in musical instruments. I know an attorney for Micron who has warehouse space for his tuba collection (which numbers in the hundreds). He can't possibly play them all. But then, people collect Beanie Babies and I haven't the faintest idea of what they're good for. It's getting tempting to run my own 8800 up the eBay flagpole to see who salutes. It's been sitting on a shelf in the garage since about 1978, when I migrated to an Integrand Systems box. Still have both, mostly because I've been too lazy to do anything about them. Speaking of old stuff, when looking for something else, I ran across the serial and RAM cards for the SWTP TV Typewriter--are they worth anything or are they better used as landfill material?
