I have a 1740KHz Max 4-bit Free Running Matrix Oscillator: 4017 Single-IC data-clock-sync processor. The Operating system is Combination Logic hard-wired into the IC, data is processed by 4 sequential logic Data type flip-flops and a few RS type flip-flops.
Any Chip thats crappier than that that does something useful will most likely never be found on the internet.

Eat my 4017 -- SN!PER.
4017 Most versatile non-PIC chip on the market.\
Larger amounts and better versions of the 4017's concept design is found in Video Processors, capture cards, processors, BIOS, I/O devices, USB ports, PICs, LED Drivers, cameras, and even your PSP.
