... I just picked up a used internal drive fairly cheaply on ebay. It's a 68-pin LVD/SE type, I do have a 68-50 pin adapter to go with it... I guess what my questions are:
1) Do you take a speed hit by going 68 pin to 50 pin via the adapter rather than using the 68 pin with the corresponding cable? I'm pretty sure the card I'll be using it with has both connector types.
2) This drive apparently doesn't have onboard termination. I take it then I need a terminator which fits on the internal cable?

Yes, you take a speed hit running it over a 50-pin connection. It is the difference between running over a narrow(8-bit) versus wide(16-bit) data bus. Now it might not be as much as the 50%, depends on other drive variables.
As for terminator, it is unusual for a LVD drive to provide termination. Some 68-50 Pin adapters do provide for termination, otherwise you will have to add a terminator to the end of the ribbon cable. It either needs to be a LVD/SE multi-mode terminator or one that matches the mode you set the card and drive up for.

SCSI refresher?
Surely it isn't that hard to pick it up and drop it in the trash is it?
(sorry - I just REALLY, REALLY hate SCSI and am SOOOO glad that I don't worry about this stuff anymore)

I worked with servers for 20 years, and that included needing to know how to set up a SCSI system. Now, even though I have been out of it for a year and a half, the knowledge is still ingrained. That said, since I started with drives before they even got to calling it SCSI, it was not all that hard. Now setting up interrupts and addresses on a backplane manually using dip switches or wire wraps, that was a pain.
