Overview
The SL-HF300 was the first USA NTSC machine to have the HF prefix.
It had the auto play feature, a 7-day, 6-event timer and was available in
silver and black. It is now fairly easy find on the used market.
When it was current, it retailed for approximately $1000 new, and was introduced
in 1984. It's big brother was the HF500.
