Great old arrangers, Donny, and a nice picture of you and your Dad.
The Korg SAS-20 was one of the first arrangers that didn't talk down to you...it sounded excellent in it's day.
I believe it won some kind of award in Sounds magazine, which was a big deal for a home keyboard.
I had a Yamaha PS-6100, and then a PSR-6300 as two of my early arrangers, the latter actually being used several times in the CBC Radio recording studio.
I still have my CS-01 (and the breath controller)...mine was the older model in silver. I play it through the mic input on my Tyros4...it takes the monophonic sound and adds harmony; sort of a pseudo polyphonic synth.
Thanks for the memories, and yes, we have come a long way from 16 or 32 styles and as many sounds (at 8-note polyphony)...plus the keys back then weren't touch sensitive and, there weren't any effects (maybe reverb) to speak of.
