Vector
Graphic ZCB Single Board Computer
The Vector Graphic ZCB board probably
represents the apex of board design at the company.
The board provided
the capability of a complete computer system on a single board. It contained the
equivalent of a CPU board, a PROM/RAM board and an I/O board, all contained on
one S-100 bus compatible board. The board contained a Z-80 microprocessor
initially running at 4 MHz but later boards were upgraded to run at 6MHz. It had
1024 bytes of static RAM memory and sockets for up to 12K of PROM. It had one
serial I/O port and three 8-bit parallel ports. Circuitry was provided to
support static or dynamic memories. All 8-bit 8080 signals were generated making
the ZCB compatible with older 8080 based systems. Input loading on the bus was
no more than 1 low power TTL load while output fan-out was capable of up to 10
TTL loads. The ZCB could be used as a
complete microcomputer in some process control applications. It was somewhat
similar in concept to the
SD Systems SBC.
