Hi all,
I am wondering if it is possible to add extra memory to a bs2p40 for
program storage. If this is possible how would I go about dumping the
runnign program and starting the next.

I could be wrong, but I don't think there is anyway of adding program memory
to the 2P - data storage, yes, program storage, no. The best thing would be
to add a slave chip like the BS2E and let it do part of the programming.

The BS2p40 has eight available program slots. You can put extra code in
other slots and call it with the RUN instruction (Note: You cannot do a
GOSUB across slots). This article provides a strategy for putting
subroutine-type code in extra slots:
One thing to consider is the use of DATA statements. If your main
program is using a lot of EEPROM data, you may want to move that to
another slot. The BS2p and BS2pe are unique in that they allow READ and
WRITE to work across slots (by using the STORE instruction to set the
READ/WRITE slot).
