"Why bother, Install NoTouch (and, if needed "the backdoor") and all you need is the RS232 interface"

Erik,
I have yet to implement NoTouch and enjoy the benefits,I keep putting it off, because I have a parrellel programmer, but recently I lost 2 PLCC devices which was soldered on the PCB and this time I am forced to implement it.

Prahlad,
Elektronika sales quoted around Rs.225/= they also quoted a similar price for a 90Kb flash in the 89C51 series, I think it ends with MX.

Regards,
John.
