Did you know that the folks at NEC announced both the PC Engine DUO and the PC Engine LT (the laptop-esque portable mentioned in this post) at the Tokyo Game Show in 1991? Well, they did.
At the same show, NEC also displayed a four-inch, clamshell monitor that could be attached to the aforementioned DUO to turn it into what the writers at TurboPlay magazine called "the ultimate portable machine."
In this article (from the August/September 1991 issue of TurboPlay), it's suggested that this sexy little monitor (above) had been released two years prior with a price tag of approximately $600. That assertion seems questionable to me, as that would mean it was released in 1989--the PC Engine's second year on the market.
So, I have a question for any fellow PC Engine fans out there who may come across this post: Was this monitor really released in Japan in 1989, or was it released alongside the DUO and the LT?
Regardless, it's a rather fascinating peripheral--especially given its release date--isn't it?
