Fluke 9000A mystery adapter (for me at least ;-)
by John Robertson 20 Feb '18

20 Feb '18

I have a pod module here called "Z8 I/F ADAPTER" Fluke #9000-200/AB. It has no cable to the base, just a 40 pin CPU cable. Inside is a couple of RAM chips, and some Fluke hybrid interface ICs. Any guesses? John :-#)#

Hey, that would be my cue :) All of the M72, M82, M84 games from Irem use a NEC V20 which is a 8086 with some extra instructions. It's also pin compatible so the 8086 pod is usable with it. Of course, there aren't exactly many of these around :) Chris (M72 = RType, Dragon Breed, XMultiply, + others, M82 = RType II, Pound for Pound, M84 = Major Title) ______________________________ Reply Separator _________________________________ Subject: 8086 pod for fluke?

Does anyone know if the scripts for the 9010 work on a 9100a?? It may also be of interest to know that someone (presumably Al Kossow) has scanned and pdf'ed a lot of the fluke manuals and uploaded them to www.spies.com/arcade. There's a fluke directory which has some 9010 scripts and the .exe to compile them, and in the TE directory there are manuals for the 9010,9100 and most of the POD's. (I presume Al wrote the scripts) Unfortunately, the user manual for the 9100 isn't there. Sigh...

RAM Tester UPDATE !!!!
by pc2jamma 01 Apr '04

Gentleman ! I'm facing a problem building the software that makes the pattern test. I only have Windows XP machines, and the way that this OS works on Parallel port is pretty different than the Windows 9x version. (Thanks to Microsoft !!!) On the Christmas holidays, my wife forced me to paint my house... Ohhh yes... you see right... And as I'm very busy on my job, I just have holidays to work on my hobbies. Is Carnaval in Brazil next week, and I'll try to make this software during theses days - Yes man... I'll trade the Carnaval by build one test Pattern Software for you guys ;) ANY HELP AND COMMENTS IS APPRECIATED !!! I'll keep you guys up to speed.

Of course... There is also the obvious.... Not to be used on any tri-stated devices! To me, this is any chip outputing on to a bus which has more than one chip's output tied to it. What happens is you chip goes to output disabled, then another chip plays with the lines, and the comparator indicates a false. I with the others, in that I trust the good reading and suspect a false as being incorrect. Many times, the false is due to loading or threshold voltages. IE the OE line reads fine on a probe, and the chip under test fails, the chip in the machine passes, but a scope shows a swing tom 0 to +3.3 volts, or something like that. The chip in the comparator works, caus it has no outputs to drive, but the chip on the board shows differently. In this case you have to examine the sources for the inputs, and the sinks for the outputs.

I have had issues with the HP clip sometimes not seating right on the chip and giving false results. Also, sometimes the chip legs can be dirty and not make a good connection.. both things to check.. Try wiggling the clip a bit on the chip and see it it changes (I do this when on) or try squeezing the clip tighter. But, as was saif before, this will not tell you if that chip is bad - only that something connected to that pin is bad.. (most likely that chip.....) Hope that helps.

I found it to be faster and more useful to rely more on the positive results it gives. You will then be left with a short list of IC's that may either be faulty, or giving false faulty results, and you can work on those alone. I have an oscilloscope on my bench so I can back up a faulty reading with the CRO probe straight away. As I test IC's in a section I use a paint marker pen or liquid paper pen to place a dot on the pin 1 corner to indicate I tested it and it is ok. (handy if you come back a week later :) ) First thing I do with a faulty reading is look at the pin on the good IC and the same pin on the test IC with the CRO, and see if they is either too fast or radically different. Apart from voltage offset differences and such caused by the comparator circuitry, you can at least see if there is a similar waveform on the IC pins that test faulty. Narrow spikes and really fast data that give false results can be seen easily. Then depending on the IC type I will either decide it looks ok with a CRO inspection using a pinout/block diagram of the IC, or pull it to test or replace. (eg fast 74161's in video sections, and some other IC's in video output especially run too quick for the comparator) Anyway hope this helps, Best regards, Marc ----- Original Message ----- From: "Martin White" <martin(a)guddler.co.uk> To: <techtoolslist(a)flippers.com> Sent: Tuesday, March 30, 2004 8:50 AM Subject: Re: HP 10529A Logic comparator > Yup comparing like for like. > > One of the guys forwarded a link to me about the bug trap comparator, and that > suggests the 157 should compare okay.

HP 10529A Logic comparator
by Martin White 30 Mar '04

30 Mar '04

Has anyone ever made a specific list of 74 series chips that this cannot successfully diagnose? Or does it depend on the circuit in which they're placed (what the inputs / outputs are tied to)? I seem to remember being told once that it can't always successfully diagnose certain logic chips. I don't have enough field experience to know when i use it if the results I'm getting indicate a faulty IC or just an IC it can't reliably diagnose. In fact, so far i don't think it's been of any use to me whatsoever. Obviously i'm ignoring those with more than 16 pins! More specifically, i was looking at some 74LS157's the other day that are part of a 2 to 1 multiplexer prior to some ram ICs. The one that had the WE lines as two of the outputs was showing a fault on both of them, but replacing it made no difference, i thus assumed the comparator was giving a false positive (or negative!). Was this right, or should i really continue to suspect that IC? It's definately in the part of the schematics where my problem lies. Please excuse if it's a bit of a dumb question to some, but i'm merely trying to familiarise myself better with some of the tools that i've picked up over the course of the last few years.
