GENERAL INFORMATION
INTRODUCTION
The Am96/4116A MonoBoard Computer (MBC) is a complete, AmZ8002 based,
16-bit, microcomputer on a single board. It is plug compatible with
the Intel Multibus board product interface. The Am96/4116A offers the
following features:
• High performance, AmZ8002, 16-bit microprocessor.
• Supports up to ei ght ki 1obytes of on-board RO~1. Two sockets are
provided with jumper selectable addressing for 2K, 4K, or 8K
bytes.
• Under software control, addresses for on-boa rd shadow
RO~1
are
mapped to off-board RAM.
• Supports up to 32 ki"\ obytes of on-board dynami cRAM.
• Two-port confl! gurat i on of RAM. RAM can be si mul taneous 1 y
accessed by the AmZ8000 and the Multibus. If both are
attempting continuous access, 50% interleave results.
• Eight fully-programmable, vectored, priority interrupt channels
wi th provi s ions for software generated interrupts. 24 source s.
• Two Ser; a
1
Communi cat ions Interfaces, one wi th full RS232C
support and the other with modified RS232C support.
• A parallel I/O interface with two 8-bit ports and two 4-bit
ports socketed for drivers or receivers.
• Programmable Timer for on-board time-of-day clock and delayed
interrupts.
