ORCA/C need 5.25" drive?

[mtm4@rsvl.unisys.com (Mike McCormick)]

I just got the ORCA/C brochure I requested from ByteWorks.  It mentions
5.25" drive among the system requiremements.  I find this hard to believe.
If it is a real requirement, then I cannot use ORCA/C on my IIGS.

Can someone tell me if this is true, before I blow $250 on ORCA/C?
