Given its history and relationship to the Alto, the Star seemed appropriate for my next emulation project. (You can find the Alto emulator, ContrAlto, here). As with the Alto a substantial amount of detailed hardware documentation had been preserved and archived, making it possible to learn about the machine’s inner workings… Except in a few rather important places.
Fortunately, Al Kossow at Bitsavers was able to provide extra documentation that filled in most of the holes. Cross-referencing all of this with the available schematics, it looked like there was enough information to make the project possible.
This is an amazing project, and the article provides a lot of details about the process of writing the emulator. I’m definitely going to try this out this week to see if I can get it running. I’ve never used the Star, and that’s likely never going to change – they’re rare, expensive, and in museums – so this is the next best thing.
I think most of us owe it to ourselves to try this out.
This is a great article. Im going to have to give it a shot later today
Hm, doesn’t the Smalltalk (or Squeek?) programming environment still include deep down the OS of Alto/Star, so emu isn’t really necessary to experience it?
