HI All, I seem to be having a problem blowing some 16c84 chips. I've tried it on 2 programmers Ive got, one from MPS and one from Magenta. Both have been used with their own software. Each time I try to programme the chip I get a verification error, normally $0000: $3FFF : <> $2810. I know the last bit means the expected code does not match, and having used the windows software with the Magenta s/w the memory map of the chip shows the section $3FFF where the problem seems to occur. Has anyone got any idea whats either gone wrong or what I'm doing wrong. TIA, -- Philip Martin email philip@philmart.demon.co.uk Royal Quays, North Shields
