Definately! I paid $19 and doen't have something that is going to tie up the
 cartrige port.

That is where I heard about it...

Yes, Electronically VERY simple, Had no problem installing one in my friend's
  520st.

This was what they suggested they do with my 1040st...
So, I took the thing apart, and saw the 16th inch thick plate of metal between
  the power supply and the ROMs, and laughed at what they wanted me to do!
Even if I did successfully cut a hole in the thing, I doubted that I would
  gain the extra 3/8" I needed.
A quick trip to Radio S. and a few hours later, I was able to make a cable out
  of 2 sockets (w/ same # of pins as the ROM) and a piece of ribbon cable.
  Thus moving the ROM socket to a spacious part of the 1040st's interior (like
  where the RF modulator should have been), and electrical taped everything.
And using the software from that ST X-Press, I was all set...

Let me tell everyone who has to hand sets their St's clock...

It is a beautiful thing when your computer boots up and knows what
  time it is...   ;)
