Hi All;
Dave, Thank You for Your input..
Remember, Or maybe You didn't see, but anyway Posting #192, and #194, States that I show a "1" in the Most left Position..
Which would make it an '8'..
On '0275, I will check, BUT Most likely I read a '0' for a 'D' in my Listing..
On '027, that was corrected back before posting #192 or so, I thought, and that we agreed must be that we changed it for the Good..
"" Are your Exx.bin files listings from the actual ROMs "" NO !!
These are from Your Hex files after I copied them to my NoteBook.. Making sure I copied Correctly, I also have to check that my main Binary Listing from my NoteBook is the same, I have done one check after I copied Your Hex files into the NoteBook.. But, I need to do another.. For clerical reasons, my writing and my typing..
As Stated in the above Posting # 199, I may have a problem in at least one of the proms, First I need to verify my Theory about what I found and secondly I then need to build a circuit for advancing the address, by another method, than by an eight position switch, which I know how to do with a single button and a Counter IC such a 74192 or 74193 or something like that..
And then I will go through all of the Proms in Pairs, also Remember that I might have at least one other prom that may be Bad, and possibly more..
Later, this week, I will as I can Actually Check out what Proms that are Readable and verify them against what we have found..
I Just want to make sure what we have typed in is correct, Before I have any New proms made..
THANK YOU Marty
