Ok, it looks like it may have already been reprogrammed as there are some utilities that I've seen listed elsewhere unless these are commonly loaded on application ROMs too.

Contents are:

BKEY KEY
SUBPROGS BASIC
CALCLEX LEX
CLOCKDSP LEX
CONVERT LEX
CUSTUTIL LEX
RPN BIN
RPNLEX LEX
STKLEX LEX
STRINGLX LEX
TEXTUTIL LEX
UNPRIV LEX
TEST32KE LEX
COORD BASIC
EPRMCPY LEX
EPRMSTWR LEX
CLONE BASIC

Please double-check the size using SHOWPORT. It's suspicious that the 32k test program would be on a 64k EPROM.
