Re: Using fluke 9010 on BZ in self test

I don't see any update sheets for the 6502. Though I could be missing them. The site isn't exactly intuitively organized :)

  I find that some games just won't work with the pod installed. It appears that the pod loads down the circuit just enough to fail...although it runs the tests just fine. Fluke does mention that in UUTs with marginal design that the pod won't work right in the RUN test.

  For example, I find in the Z80QT pod (Quick Test - late design) that there is an added 1000pf capacitor on the output lines of the Interface BCB that is not on the earlier designed Z80 or Z80/AA pods. It across A5 pins 17 and 15 (BWR & UWR).

  You might want to check the update sheets for the pods, on the FTP site (see below), these might help improve the POD response. I do need to double check that all updates are there, and if anyone sees any missing LMK or scan and email them to me or the INCOMING directory of flippers.com (tell me they are there though!).

  As for sockets to protect the POD plug, I just use regular 40 pin sockets as 'Sacrifice' pins.

    I hooked up the 9010 ran bus, ram, rom tests everything checks out fine.
     
    But when I put the board into test mode with the pod connected it doesn't bring up the test screen.
     
     
    Anyone had this problem? Any ideas on what might be happening?
     
    Oh, also anyone know a good source of turned pin sockets? I want to put sockets on the pods to protect the pins.
