It would be 3A3412.  The z80 stores 16-bit values in 'little-endian' format, or
LSB first.

Well, the .85p file format is described in
http://www.ticalc.org/pub/text/calcinfo/formats.zip.  To change this to 86p,
just replace the **TI85** header with **TI86**.  The TASM .obj file, with
$8E,$28 tacked onto the beginning, is placed where the program data goes.
That came out more confusing than I'd hoped ;)  If you have any questions, let
me know.
