You can add DEC Alpha. There was the all EISA "Jensen" / DEC 2000/300 /
DECpc AXP 150. Later Alphas came with PCI and ISA or PCI and EISA.

Some IBM RS/6000 PowerPC machines of the PReP era came with PCI and ISA.
Newer CHRP machines have a "hidden" ISA bus on the main board to connect
serial, keyboard, mouse, ... interfaces via a standard ISA "multi-IO"
chip usually found in PeeCees.

So did Sun. The "ebus" found in UltraSPARC machines is more or less ISA.
