The circuit consist of

2x 2532 32Kbit roms
|

2x 74LS393 quad 4bit counters to address roms
|

1x 74LS174 hex-d-flipflops to latch control byte
|
||||
2x 74LS139 decoder to decode rom selects
|
||||
1x 74LS161 8bit input multiplexor to select sound bit from rom data
|
||||
1x 74LS00 quad nand to decode signals (unknown) to latch control byte
|

==> 74LS139
|
||||
1x 74LS16 quad open collector inverters
|
||||
1x 74S288 32x8 Prom

The prom obviously is used to provide the right timing when

fetching data bits. This circuit should be comparable to bagman.
