The iSBC 80/16 Single Board Computer is a complete computer system that
is designed around the 8-bit 8080A-l MOS microprocessor, clocked at a
rate of 2.048 MHz.
The iSBC 80/16 board provides an iSBC 80/1OB board replacement for many
applications. The board contains 6 JEDEC-compatible memory chip sockets
(for installation of up to 64k bytes of user-provided memory), a serial
communications port providing an RS232C interface, two parallel I/O ports
providing 48 individual I/O lines, two iSBX Bus connectors providing
functional expansion by interfacing to all 8-bit iSBX Multfmodule boards,
and a Multibus interface supporting 8-bit data transfers. The board is
shipped with 2k bytes of Static RAM installed into one of the
JEDEC-compatible memory sockets.
The iSBC 80/16 board is compatible with the Multibus interface when the
board is operated as the only master on the interface, and requires the
use of a special Multibus interface control exchange mechanism if used
with another bus master. The board receives one interrupt signal from
the Multibus interface and is configurable for operation as a limited bus
master in a system environment. Compatibility of the iSBC 80/16 board
with the iSBC 80/1OB board includes compatibility with most of the
software designed for the iSBC 80/1OB board.
