Regarding my last entry, might also mention that one could download the attached Excel file to your computer and erase just the cal data (hex code). Then you would have a blank form to enter your own scope data on as you read it off the CRT display.
Another thought is that if you should lose your scope cal data, my understanding is that you could program your new RAM IC using this data. Your scope then would not be precisely calibrated, but it would be close enough to get it back in operation. Also, your recorded operating hour and power cycles would not be relevant to your scope.
Attached below is a screen print of the GQ-4X4 Programmer with my scope's cal data displayed in the buffer as if ready to be written to a FM16W08. The FM16W08 device, indicated in the upper right, has been called up from the GQ library. The reason I'm able to pull that IC up from the library is because I'm using the new "Hotfix" software from GQ Electronics, Support group.
FYI - Looking at the screen print shown, find the far left address column in pink. Then find address location "00001E00." That is where the cal data for my scope starts. That can be seen by comparing the first series of bytes "00 13 06 BF 26 EB," etc,. - to the first data points in my Excel data sheet, page 2 (attached in my previous entry) "0013, 06BF, 26EB. Those bytes should compare correctly all the way to the bottom of the screen print where once again we can compare the last bytes "00 27 00 00" - to the bottom of page 3 of my Excel spreadsheet where 0027, 0000 was copied from my scope's CRT display.
Obviously, above address location 00001E00 of the screen print, is a lot more recorded Hex data. So, what is that? It apparently it is not cal data, because it is not displayed on my scope. I believe it is non-critical stuff, like hours of operation, scope set up sequences (where one can record the scope settings by pushing a button, and then retrieving it in the future for the same setup, and who knows what else.
Correction - In my previous entry, I wrote - (Previous entry now corrected)
Note: In theory, one could manually enter this data into a programmer and then write it to a replacement IC. It would be time consuming and it would need to be double or triple checked to eliminate any errors, but it could be done. One problem with this is that, the GQ Programmer that I used here is not sophisticated enough to manually load data - per my limited knowledge.
Facts are - A friend pointed out that the GQ Programmer can manually load data! But if one was loading only what was copied off the scope CRT, it would be missing all the data we see in memory preceding the cal data. And this brings me back to the question of, is the preceding data critical to operations?
Another thought that might work (per my limited knowledge), would be to load a full set of data from another scope electronically into your RAM IC. Then go back and manually modify just the cal data part to what you had copied off the CRT display on your scope before the Dallas IC died.
I'll write more later.
