Apple 400k Single Sided Floppy Drive Refresh

Adrian's Digital Basement ][ 1h 34m Published Dec 2025

About this video

An Apple 400K single sided floppy drive, taken from the Lisa 2/5 under restoration on Adrian's main channel, gets a refresh of its own, with a Sony drive service manual linked.

Good to know: Isopropyl and other cleaning solvents are flammable and need ventilation. Linked to the wider Lisa 2/5 restoration series.

Why watch it

The linked Sony drive service manual is the reference to keep open alongside this 94 minute refresh. It sits on the second channel, apart from the main Lisa series.
