Reading Technics Player's report I just rememberd that I have several Memory cards, and that some of them were for the first technics PR Piano that came out. the Card was $170.00 USD, 16k memory and held 20 songs. I also have them for the KN800 Keyboard.
I also have 5 for Korg M3R and another for the Peavey Keyboard, a 32 k cache card. They were all in the near 200.00 price range. Is this then a matter of history repeats. These cards were in lieu of a Technics hard drive option, free standing that cost about $1200.00 USD back then. I am sure many of you will remember.
