Description
GE General Electric Technical Specifications: IS200RCSBG1BAA
Sometime later, the CPU will IS200RCSBG1BAA send out an interrupt
acknowledge (INTAK). During INTAK, the interrupt logic of
the various peripheral chips in the system will determine
the highest-priority port which is requesting an interrupt.
This device then places the IS200RCSBG1BAA contents of its 8-bit interrupt
vector on the data bus for the CPU. The interrupt condition is
maintained until the end of the INTAK cycle. Lower priority
interrupts are inhibited until this device decodes an RETI
instruction or an equivalent command.

All Z-80 devices include daisy-chain priority-interrupt logic
that automatically IS200RCSBG1BAA supplies the programmed vector (from
the highest-priority interrupting peripheral) to the CPU
during interrupt acknowledge. To ensure that more than the
on-board SIO chip can be included in the interrupt priority
loop, “look-ahead” logic has been implemented on the
board. Both ends of the IS200RCSBG1BAA board daisy chain logic have been
brought to edge connector P1 so that the board priority
within a larger daisy chain system can be established.
Board priority is determined in the same fashion as an
individual peripheral chip i.e., through the high or low state
of PCI or PCO.
The MDX-4221 is a dual-channel, serial RS-422 interface
for use with STD-Z80 microcomputer systems. The module
incorporates RS-422 (balanced, differential) serial com
munication, allowing long-distance communication (4000
ft.) in noisy industrial environments between MDX-4221’s
and/or SCU’s (Serial Control Units). Each MDX-4221
channel is capable of driving forty devices in a party-line
configuration. The module is designed around the Mostek
