  1. Mastervoice ECU (The Butler in a Box Tries again)


    http://i11.photobucket.com/albums/a1...t/CGS_7739.jpg

    Two years ago I made another blog entry discussing the Mastervoice Butler in a Box.
    As a refresher this was a late 80's product that gave you X10 home automation in a small box with speech recognition and speech synthesis. Overall it looked great on the outside but on the inside it had a number of questionable ...
  2. AT&T Personal Terminal 510A

    Here we go. Another case of Mysterious Hardware from the 80's.
    So in the early 80's while AT&T was cranking out Unix PC's and PC6300 clones one of the neglected corners of their R&D lab decided to build a terminal for the home or the office desk. Obviously they ended up never being a commercially viable product and after a few years of poor sales they were withdrawn and have pretty much vanished from existance. It seems all that remains now are a few scant magazine articles that google ...

By chance he had just bought a basketcase model 33 that he was about to trade away for a better one but the new owner didnít want the stand. A small fee was agreed on and a week later I finally had a proper stand for my teletype. It was grubby and rusty but Iím not complaining and it looked a lot better after it was given a cleaning. ...

  5. Bringing the Model 33 to the 21st Century - Part 8

    ****CLICK HERE FOR PART 7****

    Now is the point where bugs began to come out of the woodwork.
    Once the Pro Mini was programmed I began playing with sending commands to the modem using the buttons exclusively. The first issue was that single presses would repeatedly fire off commands, resulting in erratic behaviour and unreliable operation. The assumption was that the switches were inducing a level of keybounce and the micro read each instance as me pressing the button. Initially ...
