Upgrade paths

RAM

1.6 MB via Compaq's internal LTE memory expansion card · Base 640 KB soldered/on-board; expansion required Compaq's proprietary internal card, not a generic SIMM slot.

~$400 for the period Compaq memory expansion card

MODERATE

storage

20 MB internal Conner HDD (factory option), otherwise floppy-only · The hard drive was a factory-fit option (model 20 vs diskless model 1); retrofitting one into a diskless unit meant sourcing a period Conner 2.5" or 3.5" drive and the Compaq mounting bracket.

HARD

battery

Same NiCad pack, no higher-capacity official option · Original NiCad packs are long dead today; surviving units typically run on AC or a rebuilt/replacement cell pack from a hobbyist.
