<ref group="nb" name="NB_On-line_capacity">The product flyer for the [[Durango 800]] series documents a formatted "[[on-line storage capacity|on-line capacity]]" of 1.892&nbsp;MB for the diskette drives. The system, however, was equipped with two 5¼-inch [[Micropolis (company)|Micropolis]] [[100&nbsp;tpi]] 77-track floppy drives by default, and 1.892&nbsp;MB is about twice as large as the physical drive capacity documented in various other sources (480&nbsp;KB per side), therefore, by "on-line capacity" they must have meant the available storage capacity available to users for the combination of two drives.</ref>
<ref group="nb" name="NB_Brother_capacity">The sources give slightly contradicting parameters regarding the [[Brother Industries|Brother]] diskette formats. 12 sectors á 256 bytes would give 120&nbsp;KB per side on a 40-track drive, but one source claims the drives were 38-track only.</ref>
<ref group="nb" name="NB_Brother_formats">The following [[Brother Industries|Brother]] models are known to support a 120&nbsp;KB diskette format (incomplete list): WP-1 (1985/1987), WP-5 (1987/1989), WP-6 (1989), WP-55 (1987/1989), WP-500 (1987/1989). The following models are known to support a 240&nbsp;KB format (incomplete list): WP-70, WP-75 (1989), WP-80 (1985/1989), WP-3400, WP-3410, WP-3550, WP-3650D, WP-760D, WP-760D+, LW-1 (1989), LW-20, LW-30, LW-100, LW-400.</ref>
