I don't know of any way that a program can identify the difference
between a beige or platinum IIe so this does not surprise me.
The newer board just shrank the ROM and RAM chip counts by using
higher density parts. Minor difference like the shift mod jumper and
filter caps on the push button inputs would require external inputs to
be identified.
