The Jericho workstation is an example of BBN people's not being able to wait to have what they needed. Ray Tomlinson says, “Jericho was developed on internal funding because personal computer workstations were not yet commercially available. Our researchers needed personal computers that could really compute, not the toys on the market by that name. Jericho used a bit-slice architecture and ran microcoded interpreters for either Pascal or LISP. It had bit-mapped monochrome or color graphics display, keyboard, mouse, hard drive, fiber-optic network interface, sound chip, and ASCII terminal interface. It was housed in a 30 inch high rack.
