Greetings. A few months ago, I saw a list floating around, here. It listed some Seagate drives, their number of sectors, heads, cylinders, and capacity. Anyone have it? Specificly, I have a few ST-406's and have no idea what they are. The chips' date-code is from 1982 - old! It's a FH 5 1/4". Preferably, I would like to know how to format/ setup this drive with an IBM AT (as in the drive # that setup wants) Take care. (I will archive what I get and bounce to anyone) P.S. Anyone have 8" DSDD disks for sale - cheap? I just got a SOL-20 Terminal Computer and a TRS-80 Model 16B... I need 8" floppies..... Anyone? (Will pay shipping and up to @ $0.50) -- ------------------------------------------------------------------------------ If reply bounces, try "kwgst@pittvms"... no? try "fmgst@unix.cis.pitt.edu" Did you hear? Some Poles burned the Russian flag near the Soviet embassy, in Poland. :-) :-) "Nothing is impossible if you don't have to do it yourself."
