@mrcool We had touch tone very early on, and it was widespread, but the local phone companies charged to use it. Even after touch tone was pretty much ubiquitous in the 1980s, you would often find the fee on our bill (very small) and if you were pinching pennies, you could tell the to take it off and use pulse. Eventually, they dropped the fee, probably in the early 90s.
It’s not every day I get to play with a Xerox Alto thanks to the people at The Computer Museum in Maryland! I suck at Missile Command BTW. Great exhibit space and worth a visit! #RetroComputing#XeroxAlto
84-24 is a beautiful -- both technically and visually --account of restoring an original #Macintosh. A good cozy engineering read for first morning coffee.
