Seriously though, someone should make sure to snag the 7900A drive and 13215 power supply (required for the drive). These things are pretty rare and finally pretty much going out of existance. However, I must also let people who may be trying to get HP TSB running know.... I have confirmed empirically that 7906 drives do in fact work with TSB. You loose every other track on the last data surface, but it does in fact work just fine. You tell the OS and any utilities that it's a 7905. 7906's are much easier to find. I always suspected 7906's would work (all TSB docs I've ever seen specifically only mentions 7900A, 7905, and 7906A-D), but now I know for sure they work so the 7900A's aren't a given requirement.
