disk stuff (Re: GS, //e, and mystery cards)

In article <5nlnj4$7df@news.Hawaii.Edu>, I typed out with my nose:

	Looking at the other stuff I got I realized two of the disk
drives are also "MicroSCI", except "micro" is written with the greek
letter 'mu'.  One is a full height labelled "(micro)-SCI A2" and the
other is a half-height labelled "(micro)-SCI A.5".
	Perhaps some special relationship with the disk controller?
(other than being made by the same people)  Though the drives work just
as well with the Apple disk controllers.

	Also (sorta) figured out what the jumpers are for.  While all
lined up in a row, two are marked "3" and the other two "6".  I assume
meaning 13 and 16 sector.

...any special trick to booting 16 sector disks on a ][ and ][plus?
(I grew up on the //e with the privileges of whopping 140k disks, 64k
on board, lower-case text, auto repeat, and these keys: `[]\ =^)
