Quantum Prodrive 80AT

In the early days, Quantum was not the well-respected industry giant it become through the 1990s. This interesting and quite rare early Quantum is a 6 head, half-height 80MB IDE unit.

Like all Quantum drives, it was designed in California but manufactured by Japanese giant Matsushita (a company better known in the west as Panasonic).

The first owner has helpfully recorded the date of purchase: 27th June, 1991. Another hand has scrawled the drive parameters in red texta. 20 years later it still detects correctly and probably still works.
