Unique id/year of acquisition: 104/99
Name: Type 1 microprocessor boards
Type 1 microprocessor boards
Class: computer
Machine: CDCS
Notes:
Small servers in the Cambridge Distributed Computing System were based on the Z80 microprocessor. This is this first production version of the ``Type 1'', with 4K of static RAM and 1K of EPROM. The application code, typically programmed in assembly language, was downloaded over the ring interface. These systems were often used as peripheral drivers, and an area of the wire-wrapped board was left blank for special purpose interface hardware to be added.

Name: VDU concentrator boards
VDU concentrator boards
Class: computer
Machine: CDCS
Notes:
The Z80 processor was also used to make terminal concentrators to connect simple character cell VDUs to the ring. A user of a ring terminal concentrator could connect to any machine on the ring and run several simultaneous sessions. The board shown here has UARTs and line drivers to connect eight terminals. This board was connected to a Type 1 processor by a short ribbon cable. All of these boards were later redesigned on printed circuit boards.
