Semiconductor chip with a window and it's not a camera 

For reasons, I was going through boxes I hadn't touched for over ten years. I came across this old gem from my college days. It's UV erasable version of a 68hc11, which was a fairly popular microcontroller at one time. I recall recently having reason to glance over the datasheet of a sibling part. It seems so incredibly quaint and simple to me now. At the time in college, I remember being a bit overwhelmed with all the details.

@cstanhope i love uv erasable chips and i think we should bring them back

@cstanhope Look at that absolute unit.

"Fairly popular" is a slight understatement. For something like 20 years, the 68HC05/07/11 family was the most popular uC out there. In the late 90s/early 2000s more of them were produced every month than all Intel processors together in a year. And they were already showing their age by the mid 90s! The SPI bus is a Motorola invention, that got popularized by the HC11.
