a Supervisor IC is something like MAX700/701?I couldn't find them yet here in India.
There are Indian members on this forum that use supervisors, so they must be available. Sources:
Maxim, Analog Devices, Linear Technology, Dallas, Philips and as a last resort Microchip (more suspectible to noise)

I read your DOC once again but there seems to be a mysterious figure 1 & 2 in AN461 which I don't find in my version of AN461.
well they are still there in _11

Can you explain when and how to implement "notouch"
when? when you do not want to fiddle with switches and such to do ISP. How? described in the document.

Also should I remove R1 from the circuit?
is it necessary to remove R1 for proper functioning?
I do not think that makes one iota of difference, but get a supervisor.
