I think from the pocessors point of view, all 6502 based systems have
their stack at $100-$1FF, also the VCS 2600. If you watch the address-
bus, I am almost sure you will see $01FF rather than $00FF when the
6502 makes an instruction which involves the stack. The memory location
which is accessed is $00FF because Bit 8 is not relevant, but the 6502 tries
to access $01FF.
