TIstang

Hi all, new to the group. Had my original TI since 1982. When I got the collection back out, recently, I started reading the manuals that came with the PEB. In the disk controller manual I found out about the terminal resistor if you only have one drive. This explains the single disk processing option in the disk manager module. I didn't tear into the mounted disk drive to look at it but assumed it was there. Is this something that can easily be removed, stored and reinstalled when desired? Can an additional one be obtained and are they cheap? Does anyone have a pic of one? That will save me breaking mine, so to speak, to look at the one that must be on my drive. Thanks for any help!
