I used Git to download the current files, unzipped the 4.41 binary to run on my new M4 MacBook Pro (!)
Put the BAS file in the folder with SDECB, ran it and chose "compile with Makefile"
link to BAS file: https://www.dropbox.com/scl/fi/7nnyrfj5onoogq7wswmw9/SPACELAB-SDECB.bas?rlkey=tt50w2h2vay0uqwt11v3mfvw9&dl=0
