Tallgrass was significant in the history of the PC because IBM shipped its PCs for almost two years without any hard-drive option. The IBM name attracted the makers of larger, professional software products that required a hard-drive's speed and capacity. The early availability of the Tallgrass hard-drives enabled those software products to make earlier entrances into the PC market. The parallel introductions, of the IBM PC with the Tallgrass hard-drive, catalyzed the growth of the PC market compared to what it would have been without the hard-drive option.
Tallgrass was one of Seagate's earliest customers, initially purchasing ST-506 drives from Shugart Technology before the name changed to Seagate. The Tallgrass product was designed around the ST-506 hard drive, which required a separate controller between the drive and the computer (unlike hard drives today.) Tallgrass also briefly bought ST-506 drives from Seagate's licensee, Texas Instruments.[3] Later, Tallgrass bought most of its drives from Miniscribe and for a while was Miniscribe's largest customer.
