It seems like Jasmin paged in at boot, and button = page back in and reset works?
...
At least, that gets me a 'boot failed' error. Which is something.

Attempts to implement most of a Jasmin disk interface.
...
With one obvious omission: there's no way to start it? The real interface had a dedicated button, but I don't yet know what that button did. Research needed.

Makes an effort to detect Jasmin disks, and flags the target if found.
...
It'll try the Jasmin only if the Microdisc check fails; this is because the latter is preferable — it automatically boots, and is much better tested in Clock Signal terms.
