Minecraft Version

1.21.x

Version

NeoForge 1.115.1

Details

Reproduction:

1. Try to equip/unequip a peripheral to colored pocket PC
2. Pocket PC is now uncolored

Also I remember that peripherals could be applied to pocket PC through crafting, but I can't do the same on this version. Is it bug or it's no longer possible?

Thanks for the report! Crafting appears to work the same for me on 1.20.1 and 1.21.1 (NeoForge 21.1.9). It is shape-dependent — the upgrade needs to go directly above the computer:
