Ti99/4A The Final Repair? Finally a new CPU has arrived for my dreaded Ti99/4A Computer from RetroTaku in Detroit. You may be aware that I wanted to do a video about this over 2 years ago but problems upon problems have been hounding me. I did replace a lot of the memory chips to get the VDU working only to discover the keyboard did not want to work, so after many attempts I decided to swap out the main CPU!

TDL- Why you need bridge rectifiers! A little video prompted by Ultrasteve on Discord! I actually have never set down to build a full wave bridge rectifier and its something pretty simple to make! But the real cool thing is if you build them into your DC input circuits they give you polarity protection, and that IS REALLY useful!

I quite like this BOSE unit, its not hifi, but at the same time its not really junk, kinda sits in-between and at least is relatively user serviceable when you get in there - though I don't fancy my chances finding any schematics! Still they are cheap as chips on the market, and definitely a lot better than the equivalently prices sound bar.
