Looking for legitimate download locations for 2 SB maps

After seeing people mention them somewhere, I’m trying to find places to download the genuine articles for sb_galaxies and sb_emptyspace.

I think they were developed for & by TSCM but they can only be downloaded by registering for the site, which appears currently to be broken or maybe they just don’t like me. Relatively broad (i.e., > 2 mins) web searches just give me links to others’ fastdownload sites and there’s no guarantee of which versions they are or if the gatespawner files would be available.

I’d quite like to play them but if they’re restricted to special servers or communities then I’ll just give up humbly.

Does anyone know where else they might be available?
