my D.G. Nova 4... for trade

I've decided my Nova 4 is too much of a distraction, and will be looking for a new home for it. http://wps.com/NOVA4. Disk still broken, but partly debugged, definitely repairable, the worst is long over. I have full documentation plus some, software, etc. Comes with multiple terminals (D410 plus others plus parts). I will not be parting with the TP2 without GREAT inducement. I would like to trade it for a desktop mini of some sort, with some form of magnetic storage with software support. Meaning, tape OK if there's a decent tape OS (like linctape/dectape or 1/2" reel), modest memory, assembler, etc. I don't need a valuable collectable machine. I don't need speed, lots of memory, or even a disk. I do want magnetic storage, like 1/2" reel tape, or linctape/dectape (keep wishin') or equiv with user interface software support (eg. OS or tape exec). I want assembler, and maybe one compiler, Algol great, Fortran fine, whatever. 70's vintage, repairable, documented. DEC, DG, GA, rebadged, whatever. It needs to be "cute" and cosmetically decent, flaws OK. I'll consider nice machines with curious "fatal flaws" if it meets other criteria (mostly aesthetic). A desktop box or no more than 24" rack. Weight under 100 lbs. I'm open to suggestions. I'm on the road until mid-Sept, so replies will be spotty until then.
