Hi,
Picked up an ex-NOS 41CV thru the Classifieds.
Unit is in excellent condition, however does not power up when batteries inserted. Upon closer inspection, when looking into battery compartment, a pair of wires (one white, one brown, copper core) have been routed thru the cavity on the left of the battery housing, in that space used for recharge leads. They are held in place by a small black plastic block and contact cement. Haven't opened her up yet, don't want to mess with it without a bit of direction. It appears as though it is a mod for an external power supply.
The unit came with a proprietary ROM labelled "C-9B P-S APAC WT. & BAL. 12/30/93 1/1" It has a keyboard overlay labelled with "CREW, ZERO, EMPTY, PAX" etc. My guess is that it was a weight and balance calculator for an aircraft dispatcher or weight and balance authority.
1. Can anyone help me with getting the battery power reconnected?
2. Does anyone have any user instructions or other documentation for the mystery ROM?
