I checked the back of the scanner... and their are definately two 25 pin
parallel ports... one to attach to thet parallel port on the computer...
and another to daisy chain to a printer... there is another port... a 15
pin port... which i'm not sure what is used for..

now... this is the informationn i got from the drivers and software
installed on Windows NT... if it helps any...

Device: Scanner 300A4 3.00
Type: SCSI Scanner
Host Adapter: IEEE 1284.3 Rev. 1.2
Position: HA:0, Tgt6, LUN:0

I am still trying to get a hold of Microtek... to confirm..
