http://www.science.uva.nl/faculteit/museum/X1flex.html has a reference
("Click *here* for...") to a Flexowriter code.  It does have parity,
though the parity bit is bit 6.  Bit 7 is on for letters.  This
document shows a different carriage return ("NLCR") code, but in later
versions bit 8 was used.  The "tape code" notation is a bit odd --
it's given as two decimal numbers, which represent the punches to the
left and to the right of the feed sprocket holes.
