Hopefully this is correct. I'm presently mystified as to other options.

It seems like Jasmin paged in at boot, and button = page back in and reset works?

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.
