Subject: Brian Berg's Comments on SCSI Connectors.
Brian commented on bent pins on the High Density connectors. I don't
think the world need yet another $C$I connector -- unless you work for a
connector or cable company. Note that the PNP SCSI Spec calls out a 50-pin
connector, not a 68-pin connector. Our experience with the 50-pin connector,
which we have been shipping on adapters and cables for years, follows:
We go through a bunch of the SCSI 2 cables during mfg testing of host
adapters. The male pins of the high density connector often breaks after a
couple of weeks testing. At an average of 200 insertions a day, we estimate
the life expectancy of this cable to be around 2000 insertions. We aren't
sure what the specs require, but it may not be a problem for end users who
may only hook it up once or twice a month maximum.
