I'm honestly finding it hard to sympathize at all with this thread. You do have many ways to get this software, there are still disks and stuff on eBay, they're just expensive. I'm pretty sure you can make the GOG stuff work on old hardware, unless it's enhanced where they had the code and changed and recompiled the executables, but from all the stuff I've seen it was the original programs with the DOSBOX cfg files and maybe a few other supplemental files to make it work on new systems. I actually own the GOG files for some programs, I'll copy them over to my PS/1 and see if they work, but I'm almost positive they will. I saw mention of physical disks, but that's not really on the table anymore (unless you buy from ebay, etc). You're not downloading physical disks, but you can get the GOG files and copy them to physical disks. $6 is pretty dang cheap for 3 great games.
in the case of ultima games, you can still get them for other platforms under the questionable 'abandonware'. I'm guessing the PC platform is the issue here, but honestly, up until Ultima 6... the Amiga, Atari ST and likely even Commodore 64 versions were actually better due to the poor graphics capabilities in the early PC's.
