host CPU/attribute-memory interface
The host CPU/attribute-memory interface is comprised of one port of the internal DPRAM, the eight CCRs, and
necessary control circuitry. Signals HA0 and CE1 are gated together internally so that the output of the gate is
low when both signals have been asserted by the host CPU. This output is combined with REG and the decoded
address, HA(9–1), to provide the chip enable for the DPRAM and CCRs. This composite chip enable in
combination with WE or OE allows writes and reads to the DPRAM and CCRs.
subsystem/attribute-memory interface
The subsystem/attribute-memory interface is comprised of the second port of the internal DPRAM, the eight
CCRs, and necessary control circuitry. When in multiplexed mode (SSAB = 0), the combination of signals
SELZ/I and ALE(AS) allows either a positive-pulse Intel or a negative-pulse Zilog address latch-enable strobe
to latch the address on SA8 and SAD(7–0). When in the Zilog mode (SELZ/I high), the combination of read/write
[WR(R/W)], data strobe [RD(DS)], and decoded address allows ZBUS access. When in the Intel configuration
(SELZ/I low), the combination of read [RD(DS)], write [WR(R/W)], and decoded address allows IBUS access.
When in nonmultiplexed mode (SSAB = 1), SA(7–0) become the lower-order address bits, SAD(7–0) are strictly
the bidirectional data bus, and ALE(AS) is nonfunctional. All other interface signals function the same.
