Hi All;
Thank You, Dave, I am just Curious, What is Taught there in England in Schools about Our 4th of July and Independence from England.. I know what we are Taught, but, what Are You Guys taught in School ??
First, the Switch Register has to be (for my machine) in DATAPATHS mode to do anything, including a Deposit..
When in DISPLAY REGISTER it shows '177570 right off the Bat..
Also, I notice, and If I remember Correctly it isn't Correct, but, the mADRS FFP/CPU is showing '177570 as well..
So I put the switch in DATA PATHS mode (HALT is down), No lights on.. Put '177570 into the Switches Press Load Address, Address shows '177570..
I put 123456 into the Switches and Press Deposit and I have 12345 the six doesn't show up as that is in bits 16 and 17 which is beyond the word length..
So in DATA PATHS mode I have '777570 in the Address and '12345 in the Data lights..
Switching Register switch to BUS REGISTER shows '777570 on the Address lights and '12345 on the Data lights..
On FFP/CPU mode it shows '777570 on the Address lights and '177570 on the Data lights, and is the same for DISPLAY REGISTER mode..
Not Good, but, at least it is a clue to what is wrong..
I didn't put in the opposite in the Data, (54321) as at this point it would be pointless..
And I did spray the Switches, and clean them..
I switched to my other DATA PATHS Board, and tried to do a Deposit as above, NO Change..
Looking at page 4 of the Console Schematic, is the diagram for the Switches, so I am going to get out my scope and check that those signals are OK, and that what is coming into and going out of E10 (7400) is correct..
E10 is functioning fine, It put's out what is Expected..
Now to look at where is connects to on the PDR card.. E65 (74S04) on the PDR card at first, anyway..
Ohming out E10 pin 3 to E65 pin 3, I get a beep.. Ohming out E10 pin 6 to E65 pin 13, I get nothing, No Beep..
So far it's the Cable, the wire(s) connecting E10 pin 6 to E65 pin 13 is open, from the back of the connector to the back of the connector of the cable,
I suspect, that I should check all of the lines on that cable, there are NO burn or other marks on the cable, I have sprayed the connector itself with Deoxit as well as the pin connections on the Board itself..
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
With a Wire-wrap wire Soldered to a feed thru to E65 pin 13 and attached to E10 pin 6 by an Ic Clip..
IT WORKS !!!!!
I can Deposit to '177570 and it shows up DISPLAY REGISTER and I can Switch to BUS REGISTER and the LED's follow my switch settings..
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Fritzm, Your Chase Program NOW WORKS !!!!
And Dave it looks like Your Program is working also..
This will be OK, Until I have to pull some Boards, and I will forget about the Wire and pull it out !!!!
THANK YOU Marty
