This video shows how to reassemble an HP 95LX pocket computer from 1991. The video provides detailed instructions for returning your 95LX from parts to a working unit.

I recorded a set of videos recently documenting some troubleshooting of an ATARI 400 system, and the conversion from RF to composite video. There was so little info out there about this mod that I thought even my crummy video would help. 

The embedded video above is the 4th and final part that shows the composite conversion. Here are links to the other parts and some docs and forum posts I found along the way…
