[ACC] How to access Logic Outputs 7 and 8 on the RC-850?

In some places in the manual it says there are 6 Logic Outputs and 
other places, it says there are 8.

HW Manual 10-32: "Six open collector outputs are available directly 
at the DIGITAL I/O connector for remote control."

OP Manual 10-56: "Eight User Function logic outputs are provided. One 
of these are dedicated to the remote base serial data output, but 
most outputs may be reassigned using the logical I/O structure."

The "remote base serial data output" is pin 11.  This accounts for 
one the missing logic outputs but what about the other?

The front panel LEDs show 8 and the Terminal Connection Front Panel 
Display shows 8.

I listed what the manual shows as the pin out for the I/O at the end 
of this email and it does list where (if even really available) LO 7 
and 8 can be found.  I checked the footnotes in the manaul as well 
because some of these pins are multi-function.  Maybe this is listed 
in some addendum that I don't have?

Thanks for any help.

† Determined by UF latched/expanded mode, Prog. Ref. Manual p.10-1
†† If any messages are programmed including External Device 1 (Prog.
Ref. p. 4-7), then this output provides a 1 second low true pulse to
strobe the external device. If used for this purpose, UF4 should be
programmed high in all Macro Sets, and should not be manually 
commanded.
