South Africa's discs...
As much as you might slag off South Africa for various things, its ICT sector was very much avantgarde, thank you very much. Dysan were *the* brand to buy when it came to high-quality discs, as were Verbatim. There were some no-name brands, but they all were of pretty good standard. They were *always* marked as HD or SD (HD being 1.44MB on 3.5" 'stiffies' or 1.2MB on 5.25" floppies, SD being the appropriate 720K or 360K). The 80MB hard drives were still big in the early nineties.
