MAGNETIC TAPE CASSETTE ACCESSORY (TCA)
NECESSARY DELAYS FOR THE PRINTER
For printing locally or
'wherl
transmi ttil1g to a Printer, the
TCA
provides the
necessa~J
delays for all Printer operations except Carriage Return and Vertical
Tab and Form Feed. For Vertical Tab and Form Feed, use the formula for "fill"
characters in the Time Delay and "Fill" Character Table.
If
you are using your
'TeA
with a TerrniN'et
300
Printer, you will not need a delay
for Carriage Return. However,
if
YOll
are sending infor:rrB. tion to a Terminal
with a mechanical Carriage Return or some other Carriage Return method that
takes an appreciable
anlount
of time, you must use "fill" characters to supply
a delay as specified
by
the Inal1ufacture
of the Terminal to which
you
are trans-
mitting.
Note

cases. For an approxirnate 300

use

characters at ;15 eps, and

WRITING AT 120 CPS
"When writing at 120
cps,
there must be a "fill" character at the beginning of
data to be written. This allows the
TeA
to come up to speed before the valid data
is written; other1A[ise the first character of valid data would be lost. The "fill"
character is not recorded.
If it is anticipat.ed that a tape being made will be used to make a second tape
in another TeA (at 120 cps), a "fill" character should be vrr-itten at the begirming
of data. If a third tape is made from the second tape, two (2) fill characters
should be written on the first tape.
For Example: Tape 1 is written from the keyboard at 30 cps (or less) with
two (2) "fi1l" characters.
Tape
1
is used to write Tape 2 (in another
TeA)
at
120
cps. Since one
(1)
"fill" character is lost, Tape 2 has one (1) "fill" character.
Tape 2 is used to write Tape 3 (in another TeA) at
120
cps. The "fill"
character is lost and Tape
3
has no "fill" characters.
If Tape
3
was used to make a fourth tape, the first character of data would
be lost.
