I found a odd old chip, its a standard long flat rectangular black IC with legs each side, Its a 3 piece IC body, sorta ceramic like slabs with a glue in between. Sandwich like.



Its got this written on it.

IV4836 IX @IGT
10c LH/LL Link
88.43% $400

Theres another chip that came with it,

P8032 AH
l4179779
Intel 1980

I'm just interested because it sez {$400}.... & {88.43%}
Makes me think its a limited run, individually tested & worth a bit... hopefully. The {LH/LL} link bits interesting too.
