Since official support for WinXP ended a long time ago there is no legitimate way for activating WinXP. There are workarounds for this but are not considered legitimate.

Not so excellent collection as I would have wanted. The oldest AMD K5 computer no longer work on original motherboard nor has original sound-card, due the fact that my father managed to fry both when re-soldering one of audio jacks on the sound-card. He manged to create a connection between amplified audio output and PCI lane. So bye bye awesome Creative Labs sound card with built in 2 W amplifier. Also bye bye to original motherboard with full ECC protection. This ECC protection was not only for memory but for other components and CPU as well. This allowed extremely stable system even when I overclocked the CPU from 100 MHz to about 140 MHz. I no longer remember what FSB and multiplier combination I used.

Have you tried to use Wine (https://appdb.winehq.org/objectManag...ication&iId=42) in order for making Delphi work on Linux. Apparently many people managed to do so.
