#daimyo consumer electronics

IIRC, it was marketed to preteens in the early 1990s. You'd use a stylus to digitize diary entries and it would encrypt & write them to these huge, proprietary tape memory cartridges. Periodically an armored truck would pick up filled cassettes and take them to secure off-site storage facilities they built inside decommissioned missile silos. I guess they were sort of popular in Japan, but they never really took off in the US. Cost was a factor, I'm sure, plus the fact that you needed a 240V outlet which weren't and still aren't common in residential bedrooms.

Does anyone remember the "Bully Buddy"?? It was a weird little consumer robot made in 1983 (or '84?) that was marketed to parents of elementary school kids who were worried about their children getting bullied. Pretty sure they got recalled or even banned outright after a few fifth graders in Delaware had their legs broken by one of these things after they gave it's target child a swirly while it wasn't looking.
