Pethu - Hahaha CS01 / CS01II v1.10 (Pc/Free)

From the homepage:
"My first - and probably only - attempt at a hardware synth emulation!"

"The reasons for this one is purely nostalgic - I used to own one of these back in the 80's. The hardware version was manufactured by a Big Japanese Company, and it was quite popular as an entry-level, ultra-portable and above all cheap synthesizer. If there is one piece of old gear I truly miss now and then, this is it. Not for its sound, but just because it was so darn cute! Well, here it is again - in VSTi format. Hardware synth buffs and those who were there at the time, enjoy!"
