Yes, around '88. It was actually one of the last new items I bought for my 800XL when I use to use it all the time. I purchased it at a Federated store in San Diego. That, and my SpartaDos X and R-Time8 cartridges. Boy, those were the good ol' days, when you could get excited about get your hands on the new gadget for your Atari.
Now, I get excited when I get my hands on an 'old' Atari item on ebay that I haven't got in my collection yet.
Thing DO come full circle!!! LOL
