Burning 27c160 with Willem EPROM Programmer

OldFoo · Post by **OldFoo** » Mon Jun 27, 2011 7:41 pm

I would like to burn Naomi 2 bios for my mobo with Willem EPROM Programmer PCB50B with 27Cxxxx ( EPROM 16bit ) Adapter. I've got error after writing started.

Any idea what could be the problem?

Adapter: http://sivava.com/buynow.php?pd=B12

Thanks!

Did you erase the EPROM beforehand?

+ the Willem EPROM programmer has a LOT of settings you can configure (dips, etc)..

I've erased it. As I can judge settings is correct but not sure.

Hi

I've also got that burner & adaptor and have never sucessfully been able to burn any 16bit EPROM's with it, problems with power regulation while writing the chip, you will defo need the external power supply, lots of pages on the net of people failing to write these chips on that device.

I gave up in the end and brought a wellon VP-280 for this task.

Hi! Did you successfully burn the bios?

I have a Willem Programmer, PCB5.0b, the eprom dip42 adapter, a toshiba laptop PSU with an output of 19V / 3.95A and i cant burn the bios on the 27C160... It allways give me an error when writing.

Blank check is OK

Reading is OK

Burning fails...

Can anyone help me?

Thanks!

Same result, no success

I tried with an external 12V PSU as this IC required 12v stated by this manual:

Did you try to change TWP & TWC : try with

280 us

40 us

Did you try another 27C160 ( I Mean from another brand ) .

I had the same buffer problem with 29F032 serie ... If it comes from AMD , I still have buffer error , but if it comes from ST I'ain't got no problem ...
