The Black Box Era

Information on the earliest IBM portables — from the PS/2 L40 SX in 1991 (the laptop that immediately predates the ThinkPad), through the original ThinkPad 700C in 1992, all the way to the 770 / 770Z at the end of the ’90s. The machines with magnesium roll cages, seven-row keyboards, the little red nub, latches that click, and service manuals that read like love letters to repairability.

I have been parsing old manuals to generate this site. However, it is still a work in progress and experimental. Slowly getting there. Report an OldThinkPad issue on GitHub.
