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.
