    ****CLICK HERE FOR PART 1****

    At this point the itch which was the totally basic CCU in this machine was getting to me. The basic model CCU is called the UCC6. It contains nothing but the power supply, selector driver, the power supply for the paper tape reader and a selector switch for either local use of the machine for connection to a host.

  2. Bringing the Model 33 to the 21st Century - Part 1

    Before the advent of the modern CRT or dot matrix based computer terminals of the 70ís the world of the terminal was almost exclusively in the domain of teletypewriters. Large and heavy electromechanical devices that best resembled a typewriter but with a few modifications that enabled a remote device such as a computer to send it text and receive input from the keyboard or an auxiliary input like a paper tape reader.

  5. MD Data

    Iím a fan of Magneto-optical technology. Iím just going to put that out there right now.
    Itís a fantastic medium. Itís amazingly rugged, it predated the compact disc and as opposed to a CD-R or a floppy I can assure you the data on a MO will still be there 100 years from now. Minidisc is the ultimate and perhaps the last consumer form of the Magneto Optical Disk. By the early 21st century it rapidly fell out of use in favor of WORM tape technologies and larger capacity hard disks. Minidiscs ...
