I have made available an up-to-date version of ee9,
my GNU Ada emulator of the historic English Electric KDF9,
including a 32-bit binary compiled and tested on an RPi 400.

You can find it here:

The package includes copies of the pioneering Whetstone and Kidsgrove
ALGOL 60 compilers, as well as a couple of original application
programs dating from the 1960s.
