Upgrade paths

storage

20 MB internal hard drive (T3100/20 configuration) · The drive sits under the plasma display assembly; a full teardown is required to reach it, not a job for the impatient.

~$500 for a period hard drive swap

HARD

RAM

2.6 MB via Toshiba's proprietary memory expansion board · Base 640 KB is soldered; extra memory came through a Toshiba-specific card, not a generic ISA board, so period parts are the only route.

~$400 for the official expansion board at the time

MODERATE

battery

External battery pack for untethered use · The T3100 has no built-in battery, unlike the T1100 before it; the plasma display's power draw was the main reason Toshiba left it AC-tethered.
