Otherwise fairly similar to the documented Type 8646, it notoriously uses older Pentium Pro-style VRM connectors, used up until VRM 8.4. Since Tualatin CPU's require at least VRM 8.5, it stands to reason the big difference between 8646 and mine is that I can't run Tualatin CPU's without an interposer. Damn.

Still lacking the flash storage adapter for the IDE interface. Runs Alpine Linux from a pendrive. Alpine (and probably any other distro) has lots of issues with it's non-standard ACPI interfaces. At it's heyday, people tried to run Linux on it and were able to come up with some gambiarras to make it work, but those got broken when modern-day Linux transitioned nearly all ACPI stuff to sysfs.
