--- Quote ---Glad it's fixed, although I also wonder whether simply resocketing the 1A43 ROM would have had a similar effect.

As a test, I tried putting the old firmware back in and it refused to format again, so I think the failure has to do with the ROM version itself instead of just being a connection problem.


--- Quote ---It might be nice to have a copy of 1A43 on some public archive. I can see that bitsavers has archived some source code for 1A43, but I don't think we have the ROM data anywhere.

I just uploaded the contents of the EPROM to archive.org and it can be found at the following link: https://archive.org/details/1-a-43

patrick:
The Set_AutoOffset command fails with Firmware 341-0289-B (1A43) because it just wasn't there. It has been added with 341-0289-C (1A44).

stepleton:
That is an excellent reason for the command to fail!
Alex, thanks for trying a second time.

No problem! I'm glad that we've figured out the reason that it failed and I hope that this information will be helpful to more people in the future!
