Identify HP-71B software?

[mfleming]

I was fortunate enough to acquire a 71B with the latest ROM and HPIL ROM from That Place recently. It included a CMT 64K module with some survey software. I checked Sylvain's Compendium and Joe's LIF collection but could not identify the software source. Here are some details

Code:

The SDC program, when run, displays

So, is this is some sort of support software given to purchasers of a surveying program? If so, which one? I'm sure I remember seeing ABACUS somewhere. Does anyone have information on the above ROM content or on the company mentioned? Any information appreciated!
