Anyone recognize this code plug?

Does anybody have a list of the RPX- prefixed code plugs which shows what a RPX-4445A goes to? The list on Batlabs is incorrect, this is not an MX300-S code plug. It's a 24 pin standard wide-DIP package IC which appears to be a fusible-link PROM made by Harris. The actual part bears part number 51-7661K45 .

Old pricebook shows RPX-4445A = MX300-S / MX300-R DVPSCAN

I am not sure what they mean by "DVPSCAN." Apparently that would be for the DVP module, I'll check it out. It clearly isn't the channel frequency prom module.

IIRC the IC you have plugged into a daughter board in the bottom of the MX series radios and it stored the scan info. I have an MX around here somewhere with that setup.
It required a R-1801 with appropriate firmware and adapter card to program it.
