VAX Q-bus to CAMAC systems crate interface for long CAMAC branches
Bibliographic record
Abstract
The TRIUMF Central Control System (CCS) was to be upgraded to use Q-bus-based VAXs. The CCS consists of multiple computers interfaced to a CAMAC Executive Crate with long parallel branches containing multiple pairs of differential branch extenders (DBE). The Creative Electronics System SCI 2280 systems crate interface used for the Q-bus VAX requires the CAMAC operation to complete synchronously with the Q-bus cycle in less than the Q-bus timeout period. This translates to a maximum branch length of about 150 meters containing three pairs of DBEs, which was not adequate. A Q-bus-to-SCI 2280 interface was built to allow CAMAC cycles to be decoupled, when desired, from the Q-bus cycles. When cycles are decoupled, completion of the CAMAC part can be ascertained by testing flags in the interface. The interface design and operation are described and the results of tests using a VAX 3500 are given.>

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
