MARK III/2 operation manual
Both MARK III/2 data sheets list an operation manual among the machine's standard accessories, and it is not held here. Its siblings have theirs on this site: OS3-035 for the MARK III/4 and OS3-031 for the BQ-II. Until the MARK III/2's own book turns up, the BII/MKIII-2 alignment procedures cover its alignment, and the BII's manual documents the heads and audio board the two machines share. A copy is held by the Library of Congress: MX-5050MKIII-2 Operation Manual, part no. 053-042, edition 3, 48 pages.
MARK III/4, III/8 and BQ-II data sheets
The 1984 MARK III Series brochure ends its comparison grid with “For full specifications, see individual machine data sheets.” The MARK III/2's sheet is held above, in two printings; the sheets for the MARK III/4, MARK III/8 and BQ-II are not.
