yeh k so gotta willemm

tryn to burn a chip, set it up as projectteg wrote, but it wont id the chip, and sometimes will burn up to about 50% then stops and puts up an error... its a am27c256 , will that make a difference . if i do a chip read it reckons its ok, butwont verify

heres the burner itself setup for a 27c256

dont you need a jumper from pin 1 -> 31 with that chip?

-SphiNx-

tried with and without it..

im guna burn this **** in second ***

itll verify now , but still wont burn... if i go to buffer after its been 'read', the numbers are all 0's so guessin that means its got nuthn on it, yet if i do the blank test, it reckons its not



sgbl fdsgbkdlsk !

Yes you need a jumper wire. Also, when i had dialup internet i could not be online while using the willems or it would give me an error.... weird

PureCRXtasy

eh, 27c256's are UV erase chips. Are you fully erasing it before trying to reburn it?

Chris Harris

That's a weird side-effect...

you sure bout the jumper wire.. rekcons it doesnt need it on a 27.. would that just be the same as the 29 positioning, 3-31?

The picture on the program is misleading. The DIP switch setting are backwards. 12 is 1 and vice versa. I couldn't burn chip's at first. I noticed this after going over the write-up your talking about a s#$tload of times.

No, you just have the wrong board selected. Try changing to the PCB3 and viola! it's magically correct.

update;

ive had one succesful burn.. on a 27c256..

now im trying another one and im gettin the same message

itll verify the chip, its empty, and itll read it, but it wont burn..
