Hello Good people of XGecu Forum

Last year I was asking for addition of TMS2532 Vintage computer EEPROM chip. You have told me to remind you next year because no time to do it now.

It is now next year so i give you a friendly reminder that this chip is still highly requested.

Following Link contains the Datasheet
TMS2532_TI.pdf (tvsat.com.pl)
It is getting hard to find new EPROM programmers that can handle such an old chip at 25V. I think it would be a real selling point for your device if it could handle this chip as i believe your device would become a very good alternative to buying expensive and usually 2nd hand programmers from the 90's or older off of ebay.

Thank you again for your consideration

I second that. Please TMS2532 AND TMS2532A .
It was promised last year that it will be implemented this year, but obviously not done yet.

Bump :D
More vintage chip tests would be very useful indeed (8250 uart etc)

I have already bought a test sample, this old chip supports need to special processing, the current Imax is too large,VCC about 5V350mA /VPP 25V 50mA

That's unfortunate. What about the "Standard SRAM" tests? I had these on the 866II+, but that option does not exist anymore on the T56. I often need to check old SRAM chips like 6264, 6164, 662256 etc., and it's awkward to have to have two programmers connected. I'd very much prefer to have this option available with the T56 as well.

Will support in the future

Hello,

I need too the support of the TMS2532, TMS2532A, at least in read only.
For information, I mistakenly read it as a 2732, it works but only for 2k other the 4k due to the different pinout for A11 pin.
So, reading the device should not be a problem to implement...

Kind regards,

Hello Everyone,
I was wondering if there was any sort of Update on these chips? i do not see them in the supported List.

Thank you very much for any Update, maybe now I can finally use this device haha.

Kind regards

Hello,
If you want use the feedback from item at:
TMS2532-30JL CDIP24 TMS2532-35JL Electronic Components TMS2532-45JL TMS2532A-45JL TMS2532JL-35 TMS2708-45JL TMS2732A-25JL - AliExpress
Some More info, not what you ask, but may help at:
Replacing a TMS2532 with a 2732 - TI-99/4A Computers - AtariAge Forums

Changing a voltage a bit, at least if Admin say something. sorry no more help here...
i dont have any of those ICs to send he to fix it, sorry.

You may wait, or not.
