Upgrade paths

RAM

3.64 MB via seven proprietary expansion slots · HP's own memory boards were required; the Vectra's custom hard disk types, keyboard interface, and EX-BIOS extensions made it non-standard against plain IBM PC/AT clones of the era.

storage

40 MB hard disk (top factory configuration) · Factory-fitted hard disk types were tied to HP's custom BIOS tables, complicating drive swaps compared to a standard AT.
