Will Tontec 3.5 Inches Touch Screen for Raspberry Pi Display TFT Monitor 480×320 LCD Touchscreen Kit with Transparent Case for Raspberry Pi 2 Model B and Raspberry Pi B+ work with Raspberry Pi 3 model B?
Just buy cheap chink smartphone and install any linux distro.
The GPIO pinout is the same.
Only early Raspi1s have a slightly different pinout aside from fewer pins.
