I puchased a Virus KB when they first came out in 1980. While carrying it home on the subways of NYC on a rainy night, I suffered my first (of 3) heart attacks. I eventually had to sell it. Finally this year, I found a used and slightly broken KB for sale on eBay, so I bought it ceap and fixed it up. I love it. I'm starting to look at tI's but I would probably have to sell the KB to buy one. Right now, I'm down on the idea.
