[GH85Carrera]

Life jackets in 1925


Here's a scrap pile of 8-bit OTP plastic-packaged INTEL microprocessors de-soldered and removed from digital-dash-optioned cars made by GM between 1984-1987. These have 16K of programmable ROM built into the chip and are programmed to make the digits blink on and off, once you hit 85 MPH, on a 2-1/2 digit VFD readout. If you brought the vehicle above 85, you'd never know it. Psychological means to get people to slow down I suppose. Anyway, they were removed and replaced with a new microprocessor programmed to permit the dash to show true MPH, up to 199 MPH.
