This is from a 2900/3900 manual I happen to have handy, the
translation formats are the same as in the 29B for TF-10 and
TF16.

Format Code
Formatted Binary 10
Absolute Binary 16

"Formatted Binary Format, Code 10
Data transfer in the Formatted Binary format consists of a
stream of 8-bit data bytes preceeded by a byte count and
followed by a sumcheck. The Formatted Binary does not have
addresses."
"The programmer store incomming binary data upon receipt of
the start character. Data are store in RAM starting at the
first RAM address specified by the Memory Address Begin parameter
and ending at the last incomming data byte."

Note: The START CODE looks to be FF. It's really the
RUBOUT paper tape character.

"Format 10 does not function properly unless you select
NO parity and 8-bit data"

This format was originally used for paper tape input.

"Absolute Binary Format, Code 16
Absolute Binary format is a literal representation of the
data to be transfered, and no translation of the data takes
place during the transfer. There are no overhead characters
added to the data (i.e. no address record, start code, end
code, nulls or checksum). Every byte transfered represents
the users data. This format can be used to download unformatted
data such as a ".exe. file to the programmer.
 Since this format does not have an end of file character
download transfers will terminate after no more data is received
and an I/O timeout occurs."
