Because of the supply problem to pro-
duction, we are having to use two separate
logic systems for " SuperCobra". Should
you have a problem in the field, in order to
supply you with the proper parts, we will
have to know the following information:
1. Are the boards manufactured by
A. Komani
B. Stem-URL
2. Does the machine have a black box, if
so, which type of connector is on the box.
A. Is it a 3¾" long edge connector or
B. Is it a 2¾" long strain relief
connector
The second and most current logic system
is manufactured by Stern-URL. This sys-
tem does not use a black box because we
have incorporated that circuit into the
main logic system. The program in this
system is completely different and CAN
NOT be interchanged with the program
that uses the black box.
The program on the system which uses
the black box is designated by XO. The
program on the system that doesn't use a
black box is designated by RA.
Caution: The two programs cannot be
interchanged.
