main PCB (500-36 ISS 3):
1x SIGNETICS 2650A (main)
3x SIGNETICS 2636N (video)
1x oscillator 14.31818 MHz

Sound
PCB (500-38 Iss 2):
2x SIGNETICS 2650A
1x TMS5100NL
1x LM3900N
1x LM380N
1x NE555N
1x NE5008N
1x oscillator 15.625

Roms
PCB (500-40):
1x unknown DIL40
  
ROMs main PCB (500-36 ISS 3):
1x PROM 82S185
1x PROM 82S123
1x PAL12L6
1x PAL10L8
6x unknown DIL20 300mil (on backside they are labeled 2S153H,
probably from SIGNETICS, what are they?)

sound PCB (500-38 Iss 2):
1x HN462716G (5b)

roms PCB (500-40):
4x HN462716G (cp1,cp2,cp3,sd1)
1x HN462532 (sp1)
3x HN462532G (gp1,gp2,gp3)
2x HN462532 (gp4,gp5)
position sp2 is empty
all gp are probably bad, they all give an error on pin 20 during insertion
test into the programmer, and gp1 is empty.

1x 20 wires flat cable connector to main (cn9)
1x 60 wires flat cable connector to roms (cn10)
5x trimmer (mix1,mix2,soundspeech,volume,rv5)

roms PCB (500-40):
1x 60 wires flat cable connector to main (cn8)
1x 60 wires flat cable connector to sound (cn9)
