This would have been quite a big deal on your 486 back in about 1994. The displays were hard wired without any signals from the processor, and what makes this one unusual is that as well as having a couple of digits in yellow it also sports a segmented “MHz” in red. Beige boxes would have seven-segment displays lit up with the figure, and it was an unusual example of one that used to produce a clock that he believes is one-of-a-kind unless by some slim chance somebody else has rescued the same part. This was not always the case though, and a few decades ago the clock speed of a PC was its major selling point. It’s quick enough for the job in hand and that’s all that matters. Do you know the clock speed of the computer you’re reading this article on? Maybe Hackaday readers are more likely to reply “Yes!” to that question than the general public, but if there’s a takeaway it’s that for most computer users their clock speed is now an irrelevance.
