Purchase a motherboard with a new chipset to test PicoGUS on
175% of $60 goal
Some motherboard chipsets do not play well with PicoGUS. If I don't have a motherboard with that chipset to test on, I can't fix PicoGUS to work on it.
Examples of chipsets with compatibility issues:
386/486: OPTi 82C495SLC
Super Socket 7: VIA VT82C598MVP
