 I know what you mean about the DC300 carts...what a lousy design...at least from a
longevity standpoint.  I've had numerous nightmares with those cartridges in a number
of vintage systems that I've got.    Broken tension bands, sticky tape...just plain
bad stuff.   Plus, the tape transports in the 4051/4052 are fussy as can be.   I have a
4907 single 8" floppy disk drive for my 4051, and it works great, but I don't
have the proper ROMpack module to use it with the 4052, which apparently needs a different
ROMpack than the 4051 to talk to the 4907.  So far, such a ROMpack has proven elusive.

I have the Tektronix 4052/4054 File Manager ROM Packs. Can be seen here:

I should have the documentation on them also. Only problem is they are
buried somewhere in a cargo container.
Are you still looking for one?
