I'll see what I can find, its not easy finding a DB25 Terminator on the<br>
|
||
net. Do you know what kind comes with the scanner? I guess its probably<br>
|
||
a passive one, either way, let me know if you have an idea, so I can<br>
|
||
save $20. <br>

I got the scanner from the store cheaper since they were missing the<br>
|
||
SCSI card. Oh well...<br>

I have another computer with an Adaptec 152x, card and since I just<br>
|
||
recently put FreeBSD 3.2 on it which no longer supports that card, I'll<br>
|
||
give it a shot.<br>
