For 9-track the options are 800 NRZI, 1600 PE, and 6250 GCR. I still have 21 9-track tapes in my office that I need to do something with, as our last system with 3420-style round tapes is being decomissioned in the next few months.
Slightly off topic, but interesting nonetheless. I once worked on a marine seismic data acquisition system in the North Sea oil fields, and we ran the system 24/7 when we were on a job. We generated 9-track 6250 GCR tapes at the rate of about one tape every 10 minutes. We used to buy and ship the tapes by the container load (and we used a Cray to process the data...). cheers Hugh -- Radiator: the most portable, flexible and configurable RADIUS server anywhere.
