It occurred to me that adding another peripheral was an option.  That's
why I asked the experts!

Can someone qualify exactly which controllers (or class of controllers)
would work here?  And which tape drives?  By the time you add up a
controller and a drive, it could approach $1000, though.  And the drive
must be supported on your other (Linux) system.

I have one of these, although it has been flakey as of late.  Is anyone
prepared to make up (bootable) 2.11BSD tapes on TK25 cartridges?
