Sony HiFi Betamax Found in Goodwill Salvage Pile

[Captainclock]

Hello everyone, today at work I found an early 1980s Sony HiFi Betamax VCR in the salvage bin at work and its kind of a little beaten up but I figured that if it still works I might be able to sell it to a friend of mine at church who still has lots of old Betamax tapes that he wants to watch again. Model number is SL-HF300 (which is apparently the HiFi version of the SL-300 that I had posted about on here earlier this year that my friend wanted me to try and fix for him). Anyways Its missing its front panel door for the controls up front and the front display panel is cracked. Any info about this model would be appreciated.
Also When I went to try it out (it had a tape in it yet from the previous owners) it wouldn't eject the tape at first which I monkeyed around with the loading mechanism a little bit (its completely belt driven) and then finally it started to eject the tape like it was supposed to (my guess is that it just needed to "wake up" a bit since it hadn't been played in years more than likely.)
Thanks.
