ZX Spectrum 48K

I'm not sure if this unit works. I don't have a TV to test it on and I'd rather use an emulator. Hard to part from this though; I remember getting this computer from my grandfather when I was maybe 9? My father was angry because I'd introduced a virus on his 286, so I was banned access to the computer. My grandfather felt pity and gave me his ZX Spectrum, which was already quite old. I learned basic on this thing. Even though the pictures don't show it, I also have the original cassette drive and power supply.
