Hi,

I have a USB programmer GQ 4x4

My goal is to record Blackout sound eprom to 2532. Therefore I have ordered SGS M2532, TMS2532, ST M2532. I plugged a 12v supply.

First of all, I cannot fins any device in the list which corresponds to my eproms.

Then whatever the device I select on the GQ 4x4 software, which has a link to 2532, none reads the new Eproms with FF (blanked). The standard 2532 reads other characters, the other device software give "read error" messages.

Is there a problem with my handling, or is this progammer unable to read these 2532 ?

thanks

Yes ST are chinese chips.
Sgs used from Poland but UV eraser does not manage to blank them

TMS are blanked, but in write mode, with 2532 generic device, the programmer blocks immediately and returns an error message. TMS2532A read only does not work, even with a 12vdc supply and a speed of 5 (-2 in the checkbox)

The pinout and the size of the eproms are not the same. I have not tried as the hardware are different, do you think the files can be copied with a software that records on a larger eprom ?

You are right. I am busy with another type of chips.

The guy refunded me fully. But he says it is blanked on his side. I can try to read it eith 2732

No more luck with the 2732, nor ST M2732

Blank check is failing. I ll check if I can see the voltage displayed

Hi,

Thanks for the information.

It reads different at each "Read" ?!@? Any reason ?

Good to read you all.

I am not a specialist in this pinball domain. I know that I have no issue with 2732 for system 11, but did not pay too much attention to the 2532. I though it would be piece of cake.

The original speech was in French and I wanted it in English, without bridging and cutting tracks on the original board.

I will try to get HN462532 as recommended. My Ti TMS is blanked but I you write BArakandl, the guy might have erased the Tms2532 (I read it all FF) but unable to write on them.

I ll try a longer erasing time. I plugged a 12v PS

I guess you have another programmer

It is just a basic 220vac to 12Vdc transformer.

yes I could put the 2 jumpers and cut a track, but I wanted to make it clean if possible It is a Williams sys 6 speech board. My computer is 2 years old, the USB controller version is 3.0

Hi,

Just to follow up on this, I managed to erase and successfully program 2 TMS2532JL I found in the bunch of parts I have at home. They had been initially programmed for a Zaccaria Time machine. I am happy, but not fully, I still miss 1 eprom

At least I am now confident this device can record files on 2532, but not the chinese ones not the TMS2532A

Conclusion: I ordered Hitachi Eproms. It works fine. I get my speeches

Thanks
