RE: New submission for Saturn assembly version of Math and Trig benchmarks...
Using the RSTK to save the address of the TIMER2 data backup is such a PITA that's it's not worth it. Because I had to preserve the long real in A.W and B.W, the only registers I had to work with were D.W , C.W , D0 , D1 and I also had the RSTK. The problem is that the TIMER2 value is 32bits and I couldn't find a way of juggling the above regs including the RSTK without clobbering that, or at least part of it ( R4.W is used as a counter and R0.W through R3.W are all clobbered by the HP48 ROM 15digit BCD floating point math routines. ).
