I am looking for information about hooking a 4$24 Exabyte 8mm drive
directly onto the Ethernet/SCSI board on a Sequent S27.

So far no one has come forward with anything substantial. Anyway, in a quick test we decided to try connecting an Exabyte to the SCED board. The physical connections were easy enough. The cartridge tape that Sequent provides is connected by a typical 50 pin scsi ribbon connector. The system booted fine and it even claimed that it saw the drives. But any attempt to access the drives resulted in errors to the console eventually leading to a system panic. The big question for me is whether it's purely a driver problem (fixable by us) or the it's a problem with the SCED (we need Sequent to do something). We haven't had much of chance to do any real methodical testing since our symmetry is heavily used. For now, we are resigned to dumping to the Exabytes on our Vax 11/750 (It would have been retired except it's the only thing we have that will handle the exabytes). We'll post if we make any forward (or backward) progress. We will also happily listen to other peoples experience. -arnold -- Arnold de Leon arnold@jarthur.claremont.edu Computer Science Dept., HMC uunet!jarthur!arnold Claremont, CA 91711 arnold@hmcvax.bitnet
