Does anyone else miss having this level of motivation? And that's not an isolation effect on me, I gave up on trying fun things like this for a long long time now.
That doesn't mean I don't spend some time on these things. I've been doing some Atari 2600 programming, and have been playing around with an emulated IBM mainframe (TK4 on Hercules). I have also been working on a new demo effect on the Atari ST.
Note how the things I actually do follow through on, they're all working on emulators. It does give me the ability to take advantage of modern technology (such as Emacs) while still exploring the limits of old systems.
I'd like to think that getting older means you can appreciate both the old and the new, and I think my hobby projects reflect that.
