hey
the hr 16 was the first thing I bent, and tomorrow i'll get another one to bend, it's fairly easy so i'll try to describe.
you should look for the 2 rom chips. If you don't know what to look for, chech page 2 of the Tips on cicuitbenders.co.uk.
the 2 rom chips give the exact same effect. so just choose one, or use some pins of one chip, and some of the other to have more working space.
If you connect any of the pins of that chip to another pin, you'll get the effect you're looking for. So, you can built switches on connections you like, or leave al possibilities open and build a patch-bay. You then connect all the pins to a seperate connector on your housing and link them using cables. If i'm not mistaken you'll have 28 patch points, so endless possibilities.
that's all!
later
