pac1085, I copied the original 1991 SRAM data to buffer, then put it on the new SRAM. That generated the 04 Fail. I then put the 1991 SRAM back in the A5, it also failed. The data had been changed on the SRAM in both cases. I rewrote the data back to what it was when the original 1991 SRAM was initially removed, put it in the 2465b and the result was another 04 Fail and another overwrite by the DUT.
I have the .bin data from a Qservice generic “startup” 2465b SRAM. I can certainly try that.
Craig, “Can you just go beyond the error and get a normal display?”
I get 4 CRT lines and gibberish on the bottom of the screen. Can you explain to me where on the schemtic “resistor ladder circuits with your ohm meter ahead of the DAC chip” is?
Thx, Ron
