    Default Motorola R2550A tracking gen 93C46 backup

    Anyone taken a backup of the 93C46 on the uP boarch with the tracking gen option installed ?

    Dumped one without the option and the REV 3.0 firmware ....looks completely different then the R2600/A/B. Processor board is different form the 2600/A/B as well.
    Not sure if they made a new uP board for this version or if it's a R2600C vintage board being used. The Service Manual RLN4120C is NLA from Motorola .

    Will post the firmware and dump I have and maybe that will help someone down the road when I read the EPROM's
