Dock 1 compatibility

[phr@netcom.com (Paul Rubin)]

I just got a Dock 1 on closeout ($325.00 from Netstream in TX).
But its manual doesn't indicate at first glance whether its SCSI port is 
compatible with any standard card.  Does anyone know?
I'm interested in using it under Linux.

Also, is my impression from the manual that I can install only *one*
of: 3.5" low profile hard disc, slimline CD-rom, Thinkpad 2.5"
disk cartridge, or ISA expansion card?  I.e. I can't install an ISA
card and a CD-rom at the same time?

Thanks
Paul
