Well, I suppose that would depend on the availability of documentation, etc.
for the old part. It might (possibly) make sense to bypass an old
undocumented whatsit with something documented (new or not).

I don't have any info on the M200, for example (if there is such a thing).

BTW, it isn't really relevant to your point, but the Blinkenlights thingy is
TTL.
