Filed AMD release names 366 MHz AMD-K6-2 among versions introduced and shipped in volume in the just-completed Q4 1998.
Open questions and review
Exact day/month, first shipment, package/orderable identity.
No owner discrepancy decision is recorded. This does not mean there are no unresolved issues.
family variant overlap · follow up
The AMD-K6-2 family and four speed-grade records intentionally overlap across granularities; the family must not be counted as a fifth speed-grade record or used to infer an exhaustive launch-SKU list.
AMD states a May 28 family introduction and quarterly shipment totals but does not enumerate the family launch speed grades.
Follow-up: Retain the family as a family-level candidate and each speed grade only as separately evidenced variants; do not use the group as a count of five comparable SKU claims.
date inheritance · resolved no change
The exact May 28 AMD-K6-2 family date cannot be inherited by any speed-grade candidate. The 350 MHz variant is Q3 evidence and the 366 MHz 380 MHz and 400 MHz variants are Q4 evidence only.
AMD's Q4 filing identifies 366 MHz 380 MHz and 400 MHz versions as introduced and shipped in volume during Q4; it does not supply an exact date.
Follow-up: Keep the family exact date and each speed-grade interval separately typed; reject any normalization that converts quarter evidence to day or month precision.
evidence gap · follow up
All four AMD-K6-2 speed-grade timing claims are manufacturer-controlled retrospective quarter statements. They support bounded 1998 intervals but not exact first-shipment dates or orderable identities.
The Q3 filing supports the 350 MHz interval while the Q4 filing supports 366 MHz 380 MHz and 400 MHz intervals; neither resolves exact dates.
Follow-up: Retain quarter precision and flag independent contemporary or channel evidence as optional follow-up rather than filling missing dates.

These notes preserve the state at intake. Later verification is shown under Release evidence above; an original note saying verification had not occurred is not the current assessment.
Imported source reference; independent verification has not occurred.
Original research note
Typed events: AMD's January 13, 1999 filed release retrospectively states that 366 MHz versions were introduced and shipped in volume during Q4 1998. Date precision is quarter; exact day/month and first shipment are unknown.
