50-pin SCSI became archaic YEARS and YEARS ago.

Manufacturer capacity was changed to 68-pin (UW- and LVD/SE-SCSI) and
80-pin (SCA). Also various types of network-attached SCSI drives.

There are still a bunch of 50-pin drives around, usually surplus stock
from Apple and others.

I recently bought a case of Quantum-branded (but Seagate made) drives
which were sold to Apple and later surplussed by them.

These were 4 GB drives, which, then, was the largest practical drive. I
think these were intended for use on WGS95 machines.

Or on Apple Network Servers (although ANSes typically used 68-pin hard
drives, Apple DID make a 50-pin hard drive tray adapter card, although it
is not disclosed in any ANS documentation).

Of course, with 68-pin drives we have the 9-, 18- and 36-GB drives from
IBM and others. And even larger capacity drives were once made.

And, Seagate once made a 50 GB drive, although it was in a 5.25" form factor.

Alas, all of those have disappeared.

Indeed, possibly the best way of achieving 50- or 68-pin SCSI-compatible
drives is by using an ACARD "SCSIDE" adapter attached to a large capacity
IDE drive.

The firmware in the "SCSIDE" adapter cards was very, very long ago updated
to support LBA48, so ANY capacity IDE drive can, thereby, be converted to
SCSI.

That was, at one point, the ONLY way to attach large drives to certain
Macs, namely those which did not have the LBA48 "property" contained
within the O.F. boot ROM.
