Message-ID: <9330007@hpihoah.HP.COM> Date: 16 Dec 88 16:50:02 GMT References: <8043@ihlpl.ATT.COM> Organization: Hewlett Packard, Cupertino Lines: 11 The first computer that I had hands on use of was an Adage, Inc. Ambilog 200 advertised as having a 4 micro-second cycle time, 8k of 30 bit words of core, and a 300 char/sec paper tape reader/punch. This was in 1966. I am writing this on an HP 9000/350, 25mh clock, 8mb of ram, 150mb disk. This system runs Xwindows on a 17in hi res color monitor. The cpu sits under my desk in a rack. I knew practically every gate and flip-flop, and every line of operating system code on the Adage. I'm not sure that my 350 will last long enough as a product for me learn this much about it.
