[BlindMath] Gardner–Salinas braille codes?

[Bill Dengler]

John,
Thanks for emailing me.
Yes, GS6 seems quite similar to UEB (with differences in numbers and a few other symbols). Is UEB based on it, or are they both based on some other common code?
Crazy that GS numbers were rejected on a 5-4 vote!
In terms of GS8, is this essentially just for braille displays, or are there machines for writing it on paper as well?
Re Lean Math: is it available for general use now, or still a closed beta?
Finally, the GS reference pages from the Oregon State University website seem to be gone. Are they still available at a different location?

Thanks,
Bill

FYI Lean Math will, hopefully soon, become an open source project and become something really useful. To this point it has been something I did in my spare time, but I don't have much spare time, and I am not a very good software developer.

Do you find it easier to use for personal notes/scratchwork than UEB or the older Nemeth Code? It seems much more compact than the aforementioned systems, allowing for more symbols on one line and more efficient usage especially when working with long expressions. Do you use it with a Braille display or on paper? If the latter, how do you write the 8-dot symbols?
