System 32 board description

CPUs & SOUND :

The main CPU is a NEC V60 (D70615), the sound part is similar to System 18 excepts for
the PCM sounds, it uses one Z80 and two YM3438. I have not yet identified yet
the PCM chip, it may be the custom chip 315-5476A or 315-5296.

OSC :

There is two OSC on the board, OSC1 at 32.2159 Mhz and OSC2 at 50.000 Mhz.

RAM :

IC21 & IC22    2 x 32 Kb   maybe PCM work ram (*)

IC16           1 x 64 Kb   this is the Z80 working ram

IC36 & IC37    2 x 256 Kb  Nec V60 working ram ?

IC61 & IC74 +
IC62 & IC75    4 x 64 Kb   palette ram ?

IC25 > IC32    8 x 256 Kb  Dual port ram (*)

IC40 > IC47    8 x 256 Kb  Dual port ram (*)

IC63 > IC66    4 x 256 Kb  Dual port ram

IC68 > IC71    4 x 256 Kb  Dual port ram, looks to be the video memory.

CUSTOM CHIPS :

IC60  315-5242    custom ic, gate array.
IC73  315-5388    custom ic, 160 pins square chip. (color?)
IC72  315-5387    custom ic, 160 pins square chip. (video?)
IC67  315-5386A   custom ic, 184 pins square chip. (video?)
IC38  315-5385    custom ic, 128 pins square chip. (spr?)
IC20  315-5476A   custom ic, 80  pins square chip. (pcm?)
IC6   315-5296    custom ic, 100 pins square chip. (io?)

PALs :

IC51  315-5441    GAL16V8A
IC23  315-5552    GAL16V8A    on rom board (s.v.football)

JUMPERS & SWITCHES :

The is one jumper (JP3) on mother board, position is [1-2 3] (football)
The is also 1 set of 4 dipswitches and two buttons PSW1 for TEST and PSW2 for
SERVICE.
