Hello, it seems the flash has a built-in battery. It’s highly unlikely that this will still work, especially as you haven’t mentioned whether you have the charger. Otherwise, it’s a classic flash from that era: it can fire at full power or you can use the so-called
‘computerised flash mode’, which works with any camera.
The flash has a hot shoe, which should fit your camera. You can also trigger it wirelessly using a ‘PC sync cable’. However, I wouldn’t attach the flash to modern (digital) cameras, as the ‘trigger voltage’ is likely to be very high. Just bin it; the thing is certainly not worth anything anymore.
