My catweasel 4, which I assume is more or less the same thing works fine in a p3 pentium system. Is the hreaseweazle totally different?
It is. It's a small STM32-based uC that supports USB, and so can be loaded with firmware to look like a USB device on a PC USB chain. The GPIO of the uC then connects directly to the FD and tickles the signals and reads the raw data, sending it onto the PC via USB.
Tony provided the links in the response you quoted. You can buy premade GW PCBs, but the original design was just a small STM32 "Blue Pill" dev board and an FD. The BluePill was like $10 or so, making this much cheaper than KryoFLux (I believe it was designed as a rebuttal for the high priced and "walled garden" nature of KryoFlux) or other related projects like DiscFerret and/or discontinued solutions like CatWeazel (which was a plug in card and harder to support on newer machines)
