PICMG 1.0

PICMG 1.0 is a PICMG specification that defines a CPU form factor and corresponding backplane connectors for PCI-ISA passive backplanes. This standard moves components typically located on the motherboard (i.e. memory, CPUs and chipset components) to a single plug-in card. PICMG 1.0 CPU Cards look much like standard ISA cards with extra gold finger connections for the ISA bus and the root PCI bus. The "motherboard" is replaced with a simple "passive backplane" that has only PCI and ISA connectors attached to it. These backplane connections include a dedicated system slot of the PICMG 1.0 CPU and various connections for standard ISA and PCI peripheral cards. This backplane is simple and robust, with a very low likelihood of failure, given its passive nature. This allows a much lower Mean Time to Repair than classic computer motherboard approaches, as electronics associated with CPUs can be replaced without having to remove peripheral devices.[1]

gollark: Which is a 3%ish chance.
gollark: And probably increase your risk of cancer.
gollark: Seatbelts have a really low chance of saving your life, but we still use *those*.
gollark: It's a cost/benefit thing I guess, in that while you could be near-certain of avoiding it if you totally isolated yourself from society, but that would be bad.
gollark: If you *can* avoid COVID-19 somehow you're avoiding a 2% (depending on age I guess) death risk, and I'm pretty sure people regularly do things to avoid risks smaller than that.
