This is a collection of old memory chips and a DIP (Dual In-line Package) switch that I kept from old an computer I had in the 1980's. These types of memory chips have been long since been replaced by memory modules and the DIP switch once a common way to set configurations have been replaced with software settings saved in non-volatile memory. They are all sitting on a silicon wafer board containing about a hundred 386 processor chips before they are cut and mounted in the ceramic housing. Basically chips in the raw.
