Apparently 1,172 characters on that machine. No mention I could find of composability of characters, which is possible in theory (many characters are combinations of simpler characters, but combining them alters the representation, shrinking the component characters/substituting slightly different marks). Something else I didn't see mention of: can you easily switch the cylinder or the rows to get different character sets? I can imagine a business making due with ~1,000 characters because their subject matter is narrower than a newspaper would generally need.
