Attached are two photos of the Unicomp APL keyboard showing the placement of all of the APL characters. I believe this would be very helpful if someone were to try to relate the xkb configuration file to the keys - if they don't have a Unicomp keyboard. Using your keyboard.txt file (essentially a picture of the APL layout) and your config files was how I was able to map my new keyboard. These pictures may be invaluable to someone in the same situation.
I am hoping these too can be added to the standard GNU APL distribution.
Thanks.
