I concur with the anti-glare. People forget how difficult it was to read many early computer screens; low-contrast, low-brightness, and very high reflectivity. (Try looking at a modern glass-screen iMac or MacBook/Pro with the brightness on the minimum setting. Although even that's pretty bright comparatively.)

These things were *VERY* common in the '80s and early '90s. In fact, I was one of the few people who couldn't stand them; (the brightness wasn't all that great, so I didn't want to trade some of that brightness for more contrast,) and I recall how prevalent they were. Nearly everyone in an office had them.
