Seeking Advice on Casios available in 1990

[veilofavoca]

Hi! I'm trying to figure out the keyboards that were popular for consumer retail in 1990, and again in the year 2000. I have an SK-1 which is a small size, I'm also looking for medium-size and large-size sorry I dont have the correct terminology for this sizing.

Is anybody aware of what was going on then? Thanks in advance I've been going over the casio website and it's been challenging to figure out what was really going on in the world vs release dates.

Hi Matt,

That is a very interesting question. Here's another one - why is that important to you? Might help someone steer you in the right direction.

Cheers!
