AppleScanGS - Driver Info!

[Charles Turley <gbmaidsf@wco.com>]

I need some help finding a GS/OS scan driver.  Recently I obtained a CD 
titled: 'HACK to the FUTURE' (Apple Dev. CD Series - 5-92), which 
contained (among other very interesting GS/OS application programs) 
AppleScan GS.   This is a Gs/OS desktop application with the src. codes, 
that supports flat-bed scanning with; Line-Art, Greyscale or halftone 
and DPI from 50 to 300 selections, etc.

The problem is I don't seem to be able to find the system driver it's 
asking for to allow full function, with the program.   Does anybody know 
where I might obtain the correct scan driver for this IIGS program 
'AppleScanGS' - v1.0d1?  Thanks in advance for any help or information 
anybody might be able to offer.
