My fiche set has the Technical Manual, and also (in the wirelist
section) the wirelist.
Not sure how to get it to you, though. I stuck it in my industrial-grade
scanner at its highest resolution; no go. I suppose I could take photos
of it displayed on my fiche reader?
Or is there some device I can buy which is less than a zillion dollars which
can scan fiche? There are a number of things in my set (e.g. the BA11-N Tech
Manual) which aren't online, and would be useful to have.

Yes, but actually there are 6 cards: the M7269 is a dual card which goes
into the QBUS backplane, and the M993-YA which goes into the first RK05,
to convert from the two flat cables which come from the M7268.

Actually, only 16-bit DMA addresses, I'm pretty sure.

That's what is documented in Micronote #5. There is a comment in the
15-Dec-1994 DECUServe Journal that says it can be modified for 18 bits
from Alan Frisbie.
