Will this adapter work with the willem PCB3B?   Im looking to burn 27c160 and 27c320 chips, but im not sure if that adapter will work with the PCB3B?   Thanks Alot, link below to adapter on ebay

Hi,

It should work, but you may need a different cable if you're not using one of Sivava's PCB3 based programmers.  The cable won't work with Willem's programmers.

Heya, this is the one im using below.  What type of cable would I need?  It appears that the cable on the image (ebay image) is connecting to the same place that I have a cable place for on my programmer.  Thanks!

What do you mean?  I have a willem programmer, and the adapter I purchased off ebay I assume is from Sivava, since their ebay username is Sivavath.   I have the adapter here now, but can not seem to get it working with 27c160's =(

Cable is 1:1 fom adapter to programmer, signals are equal in line.
You can connect wired A19,A20 and A21.
What SW used ? What voltage settings (Vcc=5.7 or 6.2, Vpp=12.7) ?
Does your chip erased and pass blank check ?
What error message are you getting ? Is it first adress, or random adress further ?

1:1, so could I just connect the whole thing, or just ONLY A19/20/21?

Voltage I dunno, the ac adapter is set at 12 volt, which is what I use to burn every other chips I use (27c256/512/010/020/040/080) perfectly fine.  Confirmed blank, and ive also even erased them for 2 hours afterwards.  The chips are from 2 different sources that I am using.  

It starts to program, and craps out on the first byte

A19-21 are the only signals you need from the cable.

If you're going to program EPROMs, you need to know.

Unfortunately, that doesn't tell us anything.   What voltage do you have VCC set to?

If you didn't program with VCC=6.25V, they may not have been programmed reliably...  If your application can put lives or livelihoods at risk, you need to program the EPROMs reliably.  If it's for your own personal use, you can be as careless as you want.

If you're not blank checking at VCC=4.2-4.45V, you can't be certain that they're blank either...   Erasing for 2 hours is overkill and you're wearing out your EPROMs prematurely.

What is the error message?
