    I picked this little chip tester up from Borygard when I was at the Chicago Expo. Had the opportunity to actually use it for its intended purpose tonight so I shot a quick video of it. Handy tool.

    that is cool...but a bit pricy for a hobbyist.

    Toys!

    Toys!

    Calling it a toy is probably fair but at least it is a usable toy.

    That's more words than I think I've ever heard Marc say in total, and keep in mind I've seen him in person at least three or four times, lol.

    That's pretty awesome...testing ICs if you don't have a documented test pattern by testing continuity or moving to another identical board that is known to work can be a real PITA. Ironically, this thing would probably be worth more to me (a relative novice) than someone like you. You look at it in either parts savings or time savings, and I'm just like...if a 100$ tool can keep the Pinsmith out of my house once... it's PAID FOR!

    Is it the same as these IC testers on ebay?

    Rob told me he has done something to it to expand the IC's it will test. Maybe he will chime in?

    #8 7 years ago

    I bought one at expo, too. Love it!

    #9 7 years ago

    Did it come with instructions that say what chip families it can test?

    Our whole hobby...."Toys!"

    I could have a really nice car for all I've invested in the hobby....I know some people are worse..but..

    This is very cool...and useful.

    I could not find it on his website. Looks like a nice little tool to have a round. Is the one on eBay the same or has he done something else to it?

    #12 7 years ago

    The IC tester I have at shows is basically the same idea as the eBay link. However, countless hours have been spent with the manufacturer to ensure most any pinball related IC you can throw at it were included in its abilities.

    Mine will do most all 74xx series TTL ICs, CMOS ICs, literally into the thousands of chips and anything I could possibly think of for pinball related repairs. This includes the common failure WPC switch matrix ICs, LM339, ULN2803 and others.

    It's a fantastic tool and the only thing comparable that I'm aware of, are not at all portable, and cost upwards of $600-$1000 if you can find them used.

    Rob;

    Very cool little logic IC tester. All these little things coming out lately, I'm going to have to really step up my game to keep up!

    It's an undeniably cool tool. If it did 5101, 6810, 6264, 62256 memory ICs...I'd have one. Heck...I'll probably still get one...

    Looks like this one lists LM339, ULN2803, etc as part numbers it can test.

    Ebay #: 230977852262

    "This 's a powerful IC tester with a database of 74 series, 74LS series, 74HC series, 54 series, CD4000 series, HEF4000 series, CD4500 series, etc, in all over 1500 IC types."

    Think I'll pick one of these up, for under $28 shipped seems like it would save a ton of time.

    I've bought one as well for 30 dollars and it seems to work well!

    #18 7 years ago

    I picked up the device that Vid posted the eBay link and it works well to test the all the 74XX and 40XX logic and some of the linear ICs I have in my box. It did not work on a 741 op amp or the UDN7180 UDN6184.

    Interestingly, I put LEDs in the socket in any orientation and the device lights them up. It also lights up an LED numeric digit display I have in my box...

    I also picked up the transistor/capacitor/diode tester that seller has as well. It works nicely and can tell you value of capaicitors. For example, I replaced a bunch of capacitors in a 1987 machine thinking they all should be trash by now and they all were still working fine (according to the tester). It also identifies NPN, PNP, N and P-channel MOSFETs, SCRs, etc.

    #19 7 years ago

    These IC testers are very neat, but i don't think they are practical. My issue with these chip testers is you have to desolder the component off the board to test them. That kind of defeats the purpose. I mean you can test new ICs, but that does not seem very helpful.

    If you have a locked up board, you desolder everything one by one testing??? That is not a good repair method. Most 74XX and a lot of 40XX ICs can be tested with a DMM on diode test, in circuit, looking for voltage drops or powered with a logic probe using truth tables. This is far less invasive (but not fool proof by any stretch). The 74xx and 40XX ICs are all super cheap, if you have to desolder it to figure out if it is bad, just replace it?

    The CMOS RAM tester is much more practical since these ICs are often in a socket and are bad very often.

    I test new components, so I don't replace bad with bad and then scratch my head for 10 minutes, lol.

    If there's an error and I suspect an IC and desolder it, it's nice to know if that IC was indeed broken, and this tool is usefull for that. I can measure simple Logic gates with a logic probe, but don't know how to measure some others.
    Besides if an IC is broken I always place a socket, so if after replacement there's still/again an error, I can easily taak the IC out and now I can test it as well very quickly, to see if the new one blew as well (if so, than a new search starts ).

    This tester is a great tool for all pinballers, a real sweety

    Following a list, what components can be tested.

    This is a powerful IC tester with a database of 74 series, 74LS series, 74HC series, 54 series, CD4000 series, HEF4000 series, CD4500 series, etc, in all over 1500 IC types.. The commonly seen ICs are included in its test range, such as below:

    So where does one buy this doodad? I don't see it on Borygard's site.

    I looked on his site and also could not find it.

    Quoted from SealClubber:

    It's on eBay for under $30 shipped.. read through the posts again on this thread and you'll find several links or auction numbers. I bought one and just received it a few days ago. It makes testing logic chips that are socketed on old arcade boards a breeze. I was able to test 60 chips on 3 different boards (20 ICs per board) in under 30 min.. it took more time to get them back in their sockets! I guess they're hiding some of the circuitry under the ZIF socket or labels cause there's not much visible circuitry on it. I'd imagine it's identifying chips based on the voltages on each of their pins when powered up (creating a unique chip signature)..but that's just a guess. It does a nice job and is very quick identifying the chips. A marvel of a tool

    #27 7 years ago

    I like the tester but I would like to find one that will test the old Bally/Stern 6800 & 6821 chips

    #28 7 years ago

    Thanks. Ace, Borygard said that the one on ebay wasn't his and doesn't test as many chips.

    Do you remember the "Parametric Analyzer" from the late '70's/early '80's sold mainly into the amusement and gaming repair industry? It was connected it to the inputs of a dual trace scope.

    It was pretty handy back then for testing a lot of IC's in circuit when you had a catastrophic failure not allowing the board to power up.

    #30 7 years ago
    Quoted from SealClubber:

    Thanks. Ace, Borygard said that the one on ebay wasn't his and doesn't test as many chips.

    It appears these testers are manufactured in China and the units being sold on eBay can test the additional chips that were mentioned by Borygard as pinball specific. They're also sold on international B2B portals where cheap electronic components and other goods can be had for wholesale costs like Aliexpress / Alibaba -- http://www.aliexpress.com/item/Multi-functional-IC-74-CD4000-CD4500-series-IC-NO-checker-LED-Tester-Detector/937334129.html ($20.99ea for 10 pieces or more).

    Many people don't want to deal with importing stuff from overseas, but US companies often have to source products to either resell or components/materials for end goods from international sellers.. otherwise costs of end products would be far too high for most people to want to purchase it. There are sometimes shady international sellers, language barriers, product received is not the represented product, etc.. but there are also many good sellers too. Of course.. the more people that buy something for wholesale from those sellers.. the more that pop up on eBay and the more competitive it would get for the same product to be sold on eBay. That's the downside to wholesale sourcing and the internet.. but that's another story.

    Not saying there aren't additional chips the unit Borygard is able to test, but so far none of the additional chips that were mentioned are different than what is in the description on the eBay links. It's still good to support people in the hobby when you can, nothing wrong with that. You also wouldn't have to wait 3-4 weeks like you will if you order from an overseas seller.

    I for one am very glad this IC tester was mentioned by the OP because it just saved me hours of time diagnosing a few arcade boards that were purely based on 74xx logic. Found 4 bad chips and replaced. The boards still had issues, but turned out the remaining issues were bad 7805 voltage regulators.. but since I knew the logic chips were good I could diagnose elsewhere.

    That brings back memories.

    I wonder if anyone still has/uses one?

    #32 7 years ago

    If anyone wants one of mine, just email me. I can't come close to the ebay price because they cost me much more than that in bulk. I also can't comment on the ebay one as I haven't specifically used it, but it wouldn't surprise me if it was running the exact same code at this point. It sucks, as I said I've put a great deal of time into mine. Such is the way of these things though, and why the world is full of cheap knockoffs of everything.

    I also have the RAM testers available in kits or ready to use.

    Not really a case of a cheap knockoff here though, I get what you're saying for other things but this hardware already existed right? And it was originally created and manufactured by a developer in China as a logic IC tester.. so any new capabilities suggested by customers would very likely make it into the new units. Sometimes there's deals worked out to keep things exclusive, but usually that costs big $$ since it would then affect sales of the version that lacks those capabilities.

    I'm actually curious in knowing more technical details on how it identifies the chips if you know anything about it? I'm assuming voltage characteristics when the chips are powered on? Hoped you might know since you worked with the developer to get it working with some new chips. Fascinating stuff, for now I'll just marvel at it
