PIN DESCRIPTIONS
A0 ~ A19:
Address output to EPROM. Both channels share the same
address lines in a 50-50 time sharing fashion. Pin ECS
(described below) must be examined to tell who's address
is valid at any particular moment.
ANG1 & ANG1\:
Differential audio output for channel A, connect to LM324
or LM358.
ANG2 & ANG2\:
Differential audio output for channel B, connect to LM324
or LM358.
ANGD1:
Audio feedback input for channel A.
ANGD2:
Audio feedback input for channel B.
D0 ~ D7:
Data input from EPROM.
ECS:
EPROM Channel Select output. This signal is used to
indicate who's address is on the address lines. When the
ECS is low, the address is for channel A. When the ECS is
high, the address is for channel B.
If both channels share one EPROM, this signal is usually
connected to the highest address line so that each channel
uses exactly half the EPROM space. If more than one
EPROM are used, this signal is usually used by the address
decoder to select the proper EPROM.
ENV1:
Envelop input for channel A, to be connected to INT1 with
a feedback resistor.
