The old site has been replaced, as far as I plan to go for now. There were a few things on the old site that still got hits on searches, the La San Marco espresso machine and the Meade Autostar ratio calculator were the main two.
La San Marco
I gave away the La San Marco machine years ago. Originally I planned on restoring the machine, so I collected parts diagrams and other resources in preparation. Never did much with them though, but offered the resources to others from my page. I think I’ve offered them long enough now.
The Meade Autostar ratio calculator originally produced usable update images to send to the Autostar. That code stopped working when newer browsers came out. The same changes may have broken the ratio calculations. My confidence that the numbers would still be usable is low, so that page is gone.
I had a few other astronomy calculators such as eyepiece field of view. They may reappear at some point, but for now I don’t think many people will miss them.
All in all I feel confident that the new site is good enough that the old one has been taken down.
