Note that this B_CALL is not available on Cerebrus version 1.12 and earlier.
The calling routine needs to check the software version before performing the
B_CALL.
This routine is not as intrusive as GetSysInfo if all you need to know is if the
calculator is an earlier edition of the TI-83 Plus.
Return NZ if are running on a TI-83 Plus.
