# TS1500 Video Topics

How would you like reverse video on your TV screen when using your TS1500? Not only is it possible, but it’s also ridiculously simple. All it involves is installing an SPST switch, and soldering two wires. Yes, you can use the TS1500 with [John Oliger’s TMS9918A video upgrade](http://localhost/product/video-upgrade-project/). The required modification to the computer’s NMI line is MUCH easier than with either version of the ZX81/TS1000 board.
