Thanks for both perspectives (oldest chronologically, oldest in current use). You can get almost any lisp or scheme ever written "running" (I've spent the last month working through dozens - Scheme on ITS being but the latest), but I like your view on oldest in use - active and being developed/improved. It's one of the reasons I started using gambit - not only has it been around a long time, but it's actively developed, it still supports old specs, and it's not one of those kitchen sink schemes.

I think the “still in use” is a mix of “people are using it” and “the system is actively being developed/improved”. And Scheme 48 doesn’t score high on either one (the Scheme 48 website says “The current version of Scheme 48 is 1.9.2 (released April 2014).” close to 10 years ago).

Yes, that's what I thought you meant , but I wasn't sure. Technically Scheme48 (one year older than Gambit) is still usable, but it's not under development.

I would say
- MIT Scheme
- Chez Scheme
- Gambit

The oldest was Rabbit, when Steele/Sussman invented Scheme. Second was probably MIT Scheme. Perhaps third was Scheme 84 from Indiana. Then it gets complicated (i.e. when is an implementation actually “born”).

MIT must be the oldest. What is the second oldest?
