These have very little screen time but were made by Don Penningtons FX company. The larger chips (upper left hand corner) were briefly seen while Miles Dyson is Axeing the "mother chip" while at Skynet (in special edition). I later found out the "mother chip" has a special opening at that the chips slide in. The acid etched chips I'm not sure on. They resemble the CPU chip in size but are different. They are 1990s "tech" and made by Don Pennington for T2 so I love them!Mother Chip
