In the almost-UNIX front, Apollo workstations were ISA based.
SGI Indigo2 and some HP-9000 PA-RISC desktops run EISA, with the unrealized hope (same as
PCI, really) that more hardware would work with them. Few companies wrote drivers, though

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.

Around 1993/1994, I had an evaluation board for one of the 3D VR
tracker devices and was _supposed_ to write a driver for the Indigo2,
but the deal to borrow the Indigo2 fell through and I never did the
driver (and the vendor _did_ ask for the board back).
