The Intel ICE252-5100 (not the latest model by Intel and probably
newer than the one that you've used) has a 68-pin PGA-cased chip in
its bonded-out device. I never opened it to see the prints on the
chip, but it's definitely not a plain vanilla 8051. The emulator
itself is excellent, but the user interface of the PC version sucks
big time. I've heard that the latest model is much more convenient
to use.

As a side remark, why didn't you use the internal clock oscillator in
the 8051? Doesn't it work with overtone crystals? I've had a 11.059 MHz
(in order to get standard baud rates) crystal in all my projects, and
the internal osc has worked just fine.
