and 100 TPI

Original Diablo drives were also 100 TPI, and used silver colored heads, moving to 200 TPI and the more
common white ceramic heads.

Apparently, the 100 TPI Diablo heads are extremely difficult to find today. I remember all the 100 TPI
Diablo drives at a friend's company getting converted to 200.
