PBI Review Page
This
is a KPI / Supra Interface.

This is
one of the first PBI devices to drive MFM/RLL or SCSI imbedded drives it
also supported a printer. This KPI is showing off a daughter board that
hold all the SCSI and printer parameters. The original requires you to
burn a rom for your configuration and it was not possible to change the
configuration on the fly. This PBI device would make a great Master
configuration for the multiplexer. At some point in time I will make this
or a similar device on my Master Computer and move my pbi devices that
have r handler to function as slaves.
