I absolutely lusted after one to have for my own, but couldn't afford it when they were new. Then they became underpowered anachronisms and I just made do with fond memories.
About a decade after I became a developer/techie (my true calling), the Model 100 was one of those things that I decided I just had to own, so in the 2000s sometime, I found one one eBay and bought it. I've pulled it out a few times to play and it just gives me joy to own one. One of those life goals I got to check off.
I can't believe how little memory it has though! I wanted to use it to type up a blog post about it, and I ran out of space almost immediately! I think mine has 24k, and not all of it is available. It's insanely tiny. (See how long this comment is? I always write like this... A result of my original career.)
The article is pretty short, but actually has some cool info! So much stuff I never knew about the M100. The display system is crazy. The link to the manual is awesome - it never dawned on me to look. I may have to pull it out of it's box I'm the garage and mess with it.
