[Tfug] Ping - Gordon Zaft

[Choprboy]

Thanks for the info. I knew about the DSSI drive interface. The machine 
currently doesn't have a drive (removed, recently retired government 
machine), though it does have a tape drive. Looking at Ebay, RF72 and RF73 (1 
and 2GB) drives seem to come up fairly often, selling for only a few bucks.

The 4000/200 apparently maxs out at a whooping 64MB. The NetBSD support page 
says 40Tps, though I don;t see an explanation anywhere. I'm assuming it's a 
database/records type activity, transactions per second. The guy probably 
wants way to much for it, Buy It Now is set at $450, reserve may or may not 
be lower.
