There were of course dominant brands (IBM and DEC, earlier companies) but other brands had good market share and introduced innovations. Ithaca was a significant S-100 brand, the company contributed to the IEEE-696 standard. There were well over 100 S-100 brands of products, I'll call that out.

Yes, it's amazing how SMALL minicomputers were, to support computing power comparable to desk and room-sized computers of years and decades prior. Replacing old slow human and mechanical calculators and accounting systems, relay-racks of mechanical control systems in factories, and other applications in business, science and industry. They provided "computing to the people" with wired or dial-up terminals and BASIC; the beginnings of the "personal" computing revolution.

Not much change from S-100 and microcomputers, or minicomputers, or mainframes with printer and drive and I/O controllers decades ago.

As I recall I had my S100 Sol-20 Helios system last year representing S100 systems. Can't get more S100 than a Sol.
