No ultraviolet light required

This is a pretty hefty throwback. Our modern devices don’t have much use for these, but there was a time in the not so distant past where these were used for all kinds of things. Do you remember this bit of technology? The wide shot is below.

It is an EEPROM! That is, an Electrically Erasable Programmable Read-Only Memory. The title was a clue. The EEPROM was preceded by the EPROM (Erasable Programmable Read-Only Memory). The main difference is that the contents of the EPROM were erased using UV rays. The EEPROM could be erased using an electrical signal.

I don’t know where this one came from. It turned up in a random box of parts that came in with some classic systems we were adding to our stock, but doesn’t go with them.
