- Cost cut version has a duller finish to the
paint. In comparison, the original version had something that looked
like a clear coat.
- Modifications were made to the components
inside the head. The head shell from the cost cut version no longer
seems to fit on the original version. It could though with some
modifications.
- The removable expansion cartridge no longer
has the traces to hold two flash chips. Don't be deceived by the visible
gold traces that make up the 40 pin edge connector. If you open up the
cartridges, these traces go to nothing. There is no silk screen and pads
for adding the flash chips (link)
- The main processor board is called REV K.
There seems to be some minor changes in the firmware. The power on
blinking of the eyes is different between the versions. Also, there may
be some differences in the battery low voltage set points.
