ISA2 Supports full-length industry-standard 16-bit ISA expansion boards
Uses the second expansion slot at the rear panel
ISA3 Supports full-length industry-standard 16-bit ISA expansion boards
Uses the third expansion slot at the rear panel
Designated as a shared slot with PCI slot PCI3
(1)
PCI3 Supports full-length 32-bit PCI local bus expansion boards
Uses the third expansion slot at the rear panel.
Designated as a shared slot with ISA slot ISA3
(1)
PCI2 Supports full-length 32-bit PCI local bus expansion boards
Uses the fourth expansion slot at the rear panel.
