The CRT I use the most is a Sony 20" from the 90s. It looks like a million bucks close up. It just doesn't have S-Video
I have a Sony 27" wide screen CRT as well which has S-Video in...but it is widescreen.
The TV I always wanted was a Sony 20" for the medical industry which had moduals you could buy for it to add extra tuners, inputs, etc. It came with 4 inputs you could position and display over each other if you wished, like 6 different inputs of which 4 were different video types (at least)...I soooooo wish I had ever been able to afford this TV in the mid 90s when they made it.
That 13" you got there looks pretty sweet though. I just hope it doesn't scrunch the text too bad. In the 80s I had to play on a 9" or 8" portable TV and I know that distorted the text like all hell if it was at the top or bottom of the screen.
