This demo can be found in the user manual. Took a while to toggle it in, as the front panel controls are pretty quirky. Once I got the program loaded in correctly, the system seems to run fine.

These days, this might not seem like too big of a deal, but in 1974, a SCELBI owner was likely to have the only “personal” computer in town. Running any kind of program in your own house would be a huge deal. Personally, I had to show it off to my family, so it still is a big deal to me in 2013!

I started work on putting together a cheat sheet, as the SCELBI user manual is kind of wordy, yet still is missing some important concepts, that I had to learn about, the hard way

I still need to check out memory addressing for the entire 4k memory range and I/O. This might take a couple of weeks. After that I’ll open up board sets for general sales.
