+`scsi.device-42.40-a2091-openrom.txt` is Copperline's clean-room open
+A2091 ROM (unreleased at fingerprint time, `copperhf-device` branch,
+commit 90e91de2 — not the real Commodore firmware fingerprinted as
+`scsi.device-37.64-a2091.txt` above). Every pin, dialect, and the
+unlisted-NSCMD_ETD_READ64 finding are byte-identical to
+`a4091.device-42.39-openrom.txt` — expected, since its README states the
+device/SCSI/mounter code is shared with the A4091 open ROM; this run is
+a clean confirmation that the two boards' emulated behaviour actually
+matches, not just their source.
