I was tidying up and came across a bag of 30 pin SIMMs. Definite relics of the past, some were 256K and you needed 4 of these to get 1MB memory, enough to comfortably run Windows 3.11. I can't really see anyone coming to me with a computer for which these would be an upgrade. The rest were 1MB sticks, and with 4 of those, your 4MB was just enough to scrape your way into Windows 95. I'm a hoarder at heart, so I couldn't possibly throw them out, but I was wondering how I could justify keeping them, what possible use could they be?
