	This drive appears to be a replacement in an early ~~drive~~. Being a Tandon TM101-4 it is a Quad Density, Double Sided Drive capable of storing up to 1000KB of raw data (More like 800KB of usable data). I suspect the Monitor ROM has been upgraded in the system.		This drive appears to be a replacement in an early machine.

 While Mr. Tandon has used a lean organization whose performance is rated highly, it has not been perfect. Mr. Smith of Kaypro said, for example, that Tandon has slipped a bit on delivery of the thin disk drives due for assembly in September. "They have been remiss, but have cut some prices" to compensate, he said.<br>

			"The Tandon [disk] drives suck. Excuse my language. But 40 years later, the amount of pain they caused still reverberates. They were not well-made. The guys in support spent a lot of time with dealers, like a technician in Boise, explaining how to adjust the armature. And that was not their skill set. They were there mainly for how to use WordStar, how to use Perfect Filer."<br>
