Hello ,

i have GQ-4X and i try to programming TMS2532A JL with no luck.
I tried also to program the 2532A with 2732 adaptor with no luck also.
When i tried TMS2532JDL programming is OK.

The only difference i know is that 2532JDL is 25V and 2532A is 21V.

Is this eprom not supported or am i doing something wrong ?

Regards
Michael

I have exactly the same setup....and I bought 10 x TMS2532A JL and found only one of them programmed. I have also tried making an adapter to read and write as a TMS2732a under TMS2732a settings and that doesn't work.
The eprom says its supported in brackets (test) but I would like to know why it doesnt programme the other 9. I am also using an external power supply on the GQ-4X
Regards
Brinsley

Exactly the same thing.
Only 1 of the 10 eproms i have (new eproms) programmed Ok.
Also i try to program like 2732 with adaptor with no luck.
I order new TMS2532 eproms (not 2532A) and Hitachi HN462532 to see if it is OK.
When i have info about this eproms i will post back.

It is unknown compatibility issue. Only about 10% chips can be programmed, programmed chip has same production batch code with others. But read is working fine. Where do you buy those chips?

I find it very strange everyone is having the same problem...I bought my Eproms from Ebay in America....

Sounds like the programmer to me. I have also ordered some TMS2532's in a bid to see if they work but am not very optimistic now

Send some that dont work to ZLM and he can update things. As you said it has (test) next to it, so just needs refining.

Well,

TMS2532 and Hitachi HN462532 works OK.
I have now 10 item of TMS2532 and 10 items of Hitachi.
All 20 works fine.
I think something wrong only with TMS2532A.

Because it says (test)

It means that the programming/reading algorithm probably isnt finished/fully tested.

If you send a testing chip to ZLM he can improve support.
