Contact the seller and try to get the TK70. Tell him that this is no
DLT, even when it looks so. TK70 is the predecessor to DLT and can store
around 300MB. You need CompacTape II cartridges.

Well, DSSI, not SCSI.

Note that you must not leave QBus slots open if there are other cards
behind the gap. Google for the QBus HOWTO and the pdp11-field-guide.txt

If the box is a BA213 (12 Slot QBus) you have two PSUs, one for the left
half of the backplane, and one for the right. Make sure that you allways
have load on the left and right PSU or the PSUs refuse to work.
