Some of us programmed these machines (I admit that I still have some of these pieces in my basement). I was disappointed they did not show a "stinger tap." The picture of the Alto shows the first mouse the Hawley Labs mechanical mouse (which I miss for its feel). Check out the picture of the first Cisco router using Intel Multibus (with a Motorola 68k in it) looking so awkward. http://www.eweek.com/networking/slideshows/ethernet-marks-40-years-linking-… Speaking of which, I am now back in touch with my former employer and mentor. I may have mentioned him before; I worked for him ~25 years ago and learned a great deal from him, but we'd subsequently lost touch. Many years before we met, he was the chairman of IEEE committee 802.3. Before that, he was one of the developers of OS/360. I'm going to go to NJ to visit him soon; I'll see if he has any of his 802.3 slides or conference materials left. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
