Co-processing.

I decided to buy a little something for myself, so eBay was opened up and I hit “Buy It Now” on an item.

3 weeks later, it arrived from Kowloon, Hong Kong. The reason for the package? This empty socket.

As if by magic, it was filled with a suitable device:

387

Upon fitting a 387 co-processor, a jumper needed to be shorted to inform the board to use it.

CheckIt determined that the thing was working (which is good, as there are surprisingly quite a lot of fake/broken chips circulating the market).

It was then tidied up into the desk. Makes a significant improvement where a math co-processor is utilized.

A bit of fun, reminder of days gone by.
