Re: 86-89 Digital Instrument Cluster "OD" light

Sequence of test changes:

First change was to replace the ADNA #$FB with ANDA #$FA to clear both bit 0 and bit 2.

CCB1: ANDA #$FB ; CLR b2, (DRP LAST 6.25 Ms)

This resulted in toggling of the OD indicator, so I knew I had the correct bit.

Next step was to eliminate the statement where bit 0 was likely being set:

E129: BSET L0036,#$01

This was done by inserting NOPs to replace the BSET L0036,#$01.

The OD indicator stayed off with these changes during my limited testing.
