Well, I'm not positive about the Toshiba Dock, but here's what I got
with my IBM TP760EL and IBM Dock Station II. There are VGA, COM1, LPT1:, and
external floppy ports on the back of the laptop. When I put it in the Dock,
those ports are (obviously) blocked. So there are VGA, COM, LPT1:, and
external floppy ports on the Dock to use instead. Including a HD-50 SCSI
connector, some phono audio connectors. There is also a SCSI bus in the Dock
for the SCSI CD-ROM, and a full size space for another SCSI device (burner,
tape drive, etc...), two ISA expansion card slots, and a second Type
I/II/III PCMCIA slot.
	So, like Nathan is leaning to, it's probably not a second ISA bus,
but merely an add-on or replacement that supposed to take control when the
laptop is in the dock? Like switching the laptop ports off, and redirecting
(of sorts) to the ports on the back of the dock? Does this make sense, or am
I just babbling?

	And FWIW, 1.4.2 on my 760EL seems to be fine in and out of the Dock,
if I recall correctly...
