I believe the they are DS1486, and DS1250Y (from memory of reading recently) I guess maybe I should hunt the data sheets and re-familiarize myself with the beasts - I used to know something about everything Dallas had- but that was mid '90's. I started hoping I could find someone I could pay to do it and just outsource the problem, but it looks like I'm going to end up diving into the swamp.
I don't know which is the culprit but if one is replaced so should the other due to battery age, and pulling the board out and reworking one is not much less than reworking both.
I have seen on some threads, someone has designed a workalike using a non battery Dallas part allowing using an external battery
But at the moment I'm looking for assistance with how diagnose the problem further to prove that is the problem
I am getting in a Prologix IEE488 to usb adaptor in a week or so and I would like to get some instruction on how to download/upload the content
If it's one of those I should be able to clear the error at least long enough to do a self test to verify the hypothesis. I have a file someone posted for the DS1486 - I suppose that is where the error is
Anyhow just looking for some diagnostic steps I can go thru using 488 I/F. I have seen some using the floppy, but I don't have any of those and I guess you could find them online somewhere, but I think the 488 I/F will just be better, more user friendly, more robust
