Toshiba SP-690


Hey there community,

I was wondering if anyone had any information/links to information on an old console system. It is a Toshiba SP-690, though I believe they were marketed as Toshiba Boston systems. It's a three piece unit, console and two speakers. I have one that I am trying to sell but I don't have any info for people that are asking so I thought I would turn to you folks. I believe it to be from the late 60's/early 70's.

Any help would be great, thanks!
