Chip is described as having a high-resolution, multi-flexible plastic coating that feels a lot like flesh. In real life, a variety of flesh like plastics and silicone resins exist, under trade names such as Cyber Skin, UR3, Fanta Flesh and others. These plastics are what allow life sized dolls to create and maintain the fantasy of a real life partner.
Chip has an 1980s breadboard circuit board, with light-up parts, gate chips, and big LEDs. If those parts were used in an advanced AI android, it would not be able to do anything really complex. TTL logic was used a lot for early computers. ECL (faster) and then CMOS technologies were used for later ones.
