the HP15C is the only Voyager able to do that. You can "define" a "partition" with (N+1) registers, provided that N is in X-register as you execute [f][DIM][(i)]. The other (65-N) registers are for:
Imaginary part of the complex stack, if complex mode is activated: 5 registers
SOLVER: 5 registers
INTEGRATION: 23 registers
MATRIX elements, one register for each defined element
The only exception is when you use SOLVE with INTEGRATION at the same time, what needs 23 registers and not 28, as expected. The maximum available registers for a minimun register number (N=1 is minumun, even if you try 0 [f][DIM][(i)]) is 64, what gives you enough space to store an 8X8 matrix.
Before the HP15C the only calcualtor that allowed this sort of user controlled partition was... guess? Yes, the old HP41.
Cheers and best regards, my friend.
