EPROM of the day: Intel MC1702A/C – Miltary Antique

Intel who we know as a CPU company, actually got its start, and most of its revenue, by making EPROM’s (Electrically Programmable Read Only Memory).  EPROM’s were actually Intel’s most profitable product line through 1985.

The 1702A was introduced in late 1972, it holds all of 256bytes. (2048 bits). This particular device is MIL-STD-883 Class C compliant (Class C no longer is used today).  It had to undergo much more testing and process control then a regular commercial device, as well as work in higher/lower temperatures.  This particular part was made in late 1976. Sadly it has a couple missing pins, but for being 32 years old is not bad.
