My first hard drive was a cassette deck for the Atari 800. The first Mac I bought for myself, a 7100/66 had a 250MB hard drive. I sold that and bought a 7100/80 with a 750MB hard drive. Yes, you used to actually think selling a computer to pick up an extra 14MHz was... a valid idea. Do the math though, it was a 17.5% increase, lol. Anyhoo, 8 ram slots would have gone a long way towards solving the expense and slow 1066GHz speed. MacPro don't play.
