Hello,
I was referred by a member, Peter Wallace.
We are trying to recover some programs from 9-track backup tapes.
I have a 9-track drive that interfaces to an ISA bus PC through a
proprietary card. It worked the last time I fired it up (about 10 years
ago) and has been in dry storage.
Questions:
- What is the bpi density on those tapes? This thing will not read the
highest density tapes.
- Where are you located?
Well, some are 1600 BPI, some are 6250. I have verified my drive is
working at both densities (before the SCSI adapter died.)
I am in St. Louis, MO.
I am working on an FPGA interface to the Pertec formatted interface,
it ought to work, but I don't know how much fooling around it will
take to get reliable data transfers.
