Found no trouble or sign of trouble
with magtape hardware.

Found that it is advisable to put
at least JFCL's or EQIU between
FOO: 0
CONSO 224, 1
JRST .-1

NB → JFCL JFCL

JRST @ FOO → CONO 220, 17000 17400

FOO is called with JSR to wait for
mag type

This seems to be a feature
due to the 800Dpi clock having
a period of 27μs. This is "CK1"
used to step the 4-flop.

Anyway it's a trap for simple
diagnostics, but no other programs,
we think.

Tried writing file with a few
records with TECO in the system,
and then skipping to end
of file with TECO.
No trouble found.
