The Texas Instruments 99/4A
The 99/4A was my first machine, and as such it has a very special meaning for me.
I bought it at the age of 14, and this September it will be 18 years old.
I got the beige console (I have never seen the black / silver console sold in Greece)
I recently however acquired a black / silver console as well thanks to ebay.
Both consoles work great and I still use them from time to time. See my TI-99/4A page for programs and info.
