(4-bit) AM2901 and TMS1000

[sswcharlie]

Hi
be great.If you are able to post this into the Russian language group as well that would

I am still looking for (see my post of 5 years ago!) re dump of ram from TMS1000 via test mode. (not decapping)

I have just found that Russia also made the TMS1000 and known as the AM2901.

Question: - Please confirm if the AM2901 is a replica of the TMS1000 structure?
- Has anyone achieved on this group the dump via test mode for the TMS1000?
- Does the AM2901 have a similar test mode and would this work for the TMS1000?


I have a TMS1000NLP MP0186 that I wish to have dumped.
Thanks
Comments welcome

No, AM2901 is chip from AMD and it is nothing to do with TMS1000
TMS1000 has "hard-wired" program and it could be read by microscope only I think
