Actually you managed to avoid answering the questions I asked. Let's just limit to one question -
Do you have reason to believe that Honeywell Pegasus FMC software ever runs on hardware that was not manufactured and supplied by Honeywell? There are several references in the linked Honeywell document that suggest this is not true. E.g.
"When the Honeywell FMS is selected/installed on a given aircraft, the Honeywell Pegasus FM card set is installed in both FMGC/FMGECs along with Honeywell supplied MCDUs. The standard configuration on the A320 series is two MCDUs and on the A330 there are three MCDUs in the standard shipset."
