Looking for a Sencore CR7000 preferably with the adaptors. If I even began to think about paying eBay prices I'm pretty sure I'd stroke out :)

Let me be more specific: The Marian 6800/6502 pod is currently configured as a 6800. It fails Self-Test with code 00 When troubleshooting the board following the 6800 Pod Manual on page 5-9 it says to verify voltages which have checked out good. Then it says to READ@0FF0 while using the self...

I recently picked up a Fluke 6800 POD to help diagnose the 6800/6502 Marian Pod. When powering up the UUT and hitting "Learn" on the 9010A I get CTL ERR 00000000 00000001. After reading some in the 9010a Manual - I believe this corresponds to a control line failure, with the 0s and 1's...

I'm looking for a working Asteroids and Centipede PCB Want do a some testing with my new SLICE and see how it does. I could use an AR 2 Regulator board for Centipede as well if someone has one laying around.

My apologies for the confusion on this. Correct: Mainframe <-> Marian 6502 Pod; Pod self-test socket <- UUT Cable; Pod Self-Test jumper installed. Test is: Power on Mainframe -> displays power on message -> press Bus Test. What is the result? 6502 Fail 00 Now, SET-TRAP BAD PWR SUPPLY? NO...

Test Jumper is installed above the self-test socket. The one thing that I should check is pin continuity on the Protection Circuits. They have very small pins and it is possible that one isn't making good contact with the socket.

When going through the troubleshooting steps - (with all the appropriate ICs removed) I get BAD PWR SUPPLY - LOOP? - I can then go and SET-TRAP BAD PWR SUPPLY? NO and which leads to the CTL ERR 00000000 01111111 - Loop screen. I believe that is what I should be seeing. Unfortunately I do...

So I got back in the Marian board troubleshooting: Problem still is failure code 00 on startup Verified all Jumpers were correct for 6502 Verified resistors and diodes were in spec (granted they are in circuit by still read good) Pulled all 74xxx ICs and tested - all good Swapped ATMEGA - No...

I'll take a look at the schematics in the manual. Sorry I didn't realize that they were basically the same as well as double check the jumper settings. It does make it easier to compare as you posted the pics earlier in the thread so thanks for that.

This is one of the aftermarket Marian Pods so the Schematics in the 6502 manual are not the same as what this is unfortunately. I'll go over into the other thread though and see what's happening. Thanks! Edit: Umm that is this thread :)

It seems that a number of different threads exist for the various reproduction pods, so I"ll just use this one. Building some Marion 6502 PODs that I had laying around (has it really been 2 years?!) and am failing self-test with code 00. I'm seeing activity on the Data/Address lines so...

Unfortunately I wasn't able to garner much help from the forum but it's all good. Still not sure what this is JTT-012C mainboard with JTT-012 Color-3 daughter. Regardless, %20 percent has been donated.
