Hello,

i ordered five days ago the GQ-4x programmer.
The devices i want to programming is mainly eproms like 2716 and 2732
but i want to know if i can test SRAM chips like 2114, 5101 and 6810.

If it possible, how can i add the info into devices.txt.
I have spare chips to test if needed and if the tests are successful i can reply the results.

2114 - h**p://www.speccy.org/hardware/datasheet/2114.pdf
5101 - h**p://www.speccy.org/hardware/datasheet/mcm5101.pdf
6810 - h**p://pdf1.alldatasheet.com/datasheet-pdf/view/100353/MOTOROLA/MCM6810.html

For the 2114 I was able to make an adapter via a bread board and test it via the 62256 test with limitng the code segment size to 1024.

I do not have details on the others, sorry.

All of those you can make adapters to test it. Use ADP-023,CPT-022,CPT-039 with self pin mapping from datasheet.

You can add following lines into devices.txt file:

Name="NTE2114",ID="XXXX",Class="DS1230Y",Category="SRAM",MFG="NTE",VCC="5V",Codesize="1024",Adapter="ADP-023,CPT-022,CPT-039 with Self pin mapping",Message="Uncheck the verify, only use Write to test ";
Name="MCM5101",ID="XXXX",Class="DS1230Y",Category="SRAM",MFG="Motorola",VCC="5V",Codesize="256",Adapter="ADP-023,CPT-022,CPT-039 with Self pin mapping",Message="Uncheck the verify, only use Write to test ";
Name="MCM6810",ID="XXXX",Class="DS1230Y",Category="SRAM",MFG="Motorola",VCC="5V",Codesize="128",Adapter="ADP-023,CPT-022,CPT-039 with Self pin mapping",Message="Uncheck the verify, only use Write to test ";

Hi,
First sorry for reviving this old thread.

I'm using a GQ-4X programmer and followed the steps described here: I made an adapter wiring two sockets and connecting equivalent pins following 2114 and 62256 datasheets.

I added your devices description to the file and restarted the app.

I selected the 2114 from teh devices list on the app and connected the adaptar to the ZIP socket on the position shown on screen (close to the bottom).

I put a SRAM chip on it and the write tested with the buffer filled with 0xFF.

The programmer told the was an error:

Write failed, Address=0x00003A, Buffer=0x10 Device=0xF0

I tried 4 different chips, all of them with this very same error.

¿What could be wrong?
I left I/O 4-7 pins on the 62256 socker unconnected, also the -OE control line. IS this right?

Do you have some schematics of the adapter to follows as instructions?

Thank you

Try different speed.

OR you chip is a bad chip.
