Shugart Associates

Although Shugart Associates did not market items directly for Heathkit computers, Heath Company used the SASI interface for it's Z-67 Winchester Disk Drive System.

Shugart Associates created both the 5 1/4" Floppy drive and the SASI and SCSI standards.

Here are the specifications for SASI (Shugart Associates System Interface).
