Greg, I used to have a couple of '50s and did maintenance on them.

From what I recall you can pull the MTI cards no problem and that will work
just fine.

As to the external disk, you do have to worry about termination. You didn't
say what kind of disks they were, or if you don't know that, what size they
are. I guess the easiest thing to do it look on the paddle card that
connects to the external disk. It should say ST506 or something else (SMD?
I can't recall exactly).

Before you remove a disk, you ought to update your boot files and make sure
that you can boot up without referencing the disk you're removing.If there
is a file system partition on the disk to be removed, you have some LMFS
work to do before you deal with the boot files.

The ST506 disks, 140MB or 190MB 5-1/4 inch drives, have a small yellow
terminator chip on them, maybe a half inch long. There should be one in the
chain, on the last disk.

The larger disks, which were typically 8 inch drives, had a small
terminator card that sits right next to where the larger of the two cables
enters the drive. It is maybe 3 inches by 1.5 inches. This again should be
on the last disk in the chain.

Hope this helps,

Paul
