Found this interesting chart from Intel showing market share in the 80s for PCs, 90s for Data Centers: https://www.extremetech.com/wp-content/uploads/2018/05/Intel-Business.jpg Definitely shows Atari, Inc. blew their early lead with the 400/800 by not opening the hardware for developers, or investing in getting the hardware costs down earlier. (Also no thanks to FCC noise requirements that made for a costly computer). There's enough in the 80s section for other conclusions on Apple, Commodore, etc too! The 90s are interesting for a variety of reasons, especially seeing separate graphs for IBM RISC and CISC based server products..
