I know someone who built a business selling software on such systems. Business BASIC -- so basically, regular BASIC with COBOL-like data access primitives and decimal math. The machine had 64 KiB of RAM and could support 8 users at once. Even when I was growing up, a machine with 64 KiB wasn't worth really taking seriously. Those were for kids like me -- the C64 and that. But back in the 70s they ran whole businesses on one.
