- Something like a Dilog DU132 or DU142 would allow 4 of them to be connected.
- If you get the original DEC controller it allows 1, but since that is really
- a Dilog DU132 with castrated microcode, you might be successful swapping in
- DU132 eproms to let you run both on the single controller.
-
- Unibus controllers should be VERY cheap these days.

- The TU80 is a decent CDC drive. You might want to avoid back-coated tapes
- like 3M's Black Watch (#700), but I don't want to start a religous war here.
- Some folks LOVE #700 in those drives despite DEC's dire warnings.
