On the subject of pointers and addressing, remember that the instruction store
is 8K words, but jump addresses are still restricted to the bottom 2K of that
store because there are only 11 address bits in the jump instruction. Thus if
you wish to return to the start of a list of commands, this must be below the
2K boundary.
On the front panel there are 5 LEDs, one for 'N', stretched to 10mSec., one for
'RUN' or GO, which comes on when the LP1342 is executing a list, and three
showing which trigger is active.
These Trigger Code LEDs come on when a non-zero trigger is received and will go
off when the list is completed.
If a trigger is received when triggers are not enabled, it will simply be
ignored. (Early units of this type did not do this).
8. Physical and Electrical
The module is a single width CAMAC unit, with rear mounted 40-way ACB header,
front panel 9-way Cannon socket Trigger Input connector, six LEMO sockets and
five LEDs.
