Code programming error at 0000

[goldscott]

I've been trying to program the 16f84a with the epic plus and the zif adapter.
i'm using a 19.3V DC power supply with plenty of current.
I have a previously programmed chip that somebody gave me, and a blank chip as well. when i "blank check" the programmed chip, EPICwin says it's blank.
i get the "Code programming error at 0000" error when i try to program the blank one.

the only problems i can think of is that i'm using a 25 to 9 pin cable, and then and adapter from 9 to 25 because i don't have a male to female 25 cable.

also, there are 3 pairs of jumper pins on the zif, the bottom 2 are jumped, 8-18 pin, exactly how the zif adapter came in the mail.

i've tried programming the chips on the epic board without using the zif, but i get the same results...

any suggestions or help?
