I have one too, the second one I've owned (my first one went AWOL

it's a big paperweight without the microcode

Agreed.
the 725 was a cab with an integreated internal/etc
rc25 combo.
memory is very limited .
It has the same backplane as the original model 11/730 - so IIRC, you
_can_ stuff 5MB in it (even though DEC said 3MB was max). It's also
possible to stick a Unibus tape cable in the slot the terminator
normally goes to, and hang a BA-11 off the side. It's no longer
compact and portable, but depending on what you want to do, it's
really handy (the PSU is _not_ particularly beefy - I would hesitate
to put high-draw cards on the internal backplane, like a UDA50 or
DEUNA... in fact, I specifically sought out some 3rd party RAM that
used a smaller number of a higher density chip than the standard 1MB
boards from DEC, just to give myself some extra margin).
your tape drive wheel may be mush with age,
so try to check it before sacrificing your ony boot tape ;0
Good advice. TU58 capstans are notorious for turning to goo.
