As a Super Socket 7 aficionado, I find the range of CPUs available for the socket most interesting, with a large range of non-Intel CPUs including the AMD K5 and K6 series of CPUs, the IDT WinChip, the Rise mP6, and of course the Cyrix Range of 6x86, 6x86MX and MII CPUs. As Socket 370 replaced Socket 7, this more or less fell to the wayside - but VIA did release Socket 370 CPUs. This started with what would become the VIA C3 core branded as a Cyrix III (VIA had purchased Cyrix in 1999). A brief history As an aside, there was a 'real' Cyrix III developed with a core derived from an evolution of the the Cyrix MII CPUs (with PR ratings and all). You can see this from the original media release, dated February 22, 2000 for the 'Joshua' core CPUs. These were never released to market. The 'Samuel' core was based on a IDT WinChip design, which VIA had also purchased in 1999. The media released dated June 6, 2000 hinted at the change in direction. The focus shifted to the power consumption benefits over the Intel competition thanks to the IDT design. For example, the 550 MHz Cyrix III CPU I'm using in this build has a power consumption of 14 watts. For comparison, a Pentium MMX 233 MHz has a power consumption of 22 watts. This allows me to use a basic Socket 7 CPU cooler rather than anything more elaborate. The parts I've wanted to put together a Socket 370 Cyrix III system for quite some time, but it has taken years to get the components sorted. Motherboards with specific Cyrix III support are quite difficult to find, although I suspect a number of boards with VIA chipsets would support the CPUs (despite documentation hinting otherwise). I purchased a Cyrix III 550 MHz CPU back in 2016 from a eBay seller based in Greece. Allegedly it had been sourced from a computer that once resided in a Japanese primary school, but who knows to the authenticity of that rather specific story. Since then, I've been looking on and off for a suitable motherboard. Luckily a Gigabyte GA-6VXC7-4X-P motherboard was recently listed on eBay in as new condition, which specifically lists Cyrix III support. This is based on the VIA Apollo Pro 133A chipset (or VT82C694X). It arrived safely and looked unused. The rest of the parts are thankfully less specific, with a standard AGP 4x slot and SD-RAM.
