There were also PC compatible systems based around ISA backplanes. This was especially common for industrial computers but Zenith/Heathkit made ISA backplane based systems for the business and consumer markets. I own a Zenith Z-160 luggable computer from 1984 which uses an 8 slot 8-bit ISA backplane. 1 slot is occupied by a CPU card which also has the keyboard connector. My system has 2 memory cards which each provide up to 320k along with a serial and parallel port. Zenith sold a desktop version of this as the Z-150. They later released models based upon 16-bit ISA backplanes. I think but am not sure of the top of my head that the last CPU they produced a 16-bit card for was the 486.
