Chip Tester Pro V2

(22 customer reviews)

A new revision of the Chip Tester is in the works and will be announced in the near future. You can register for the BackBit Forum (forum.backbit.io) for updates.

The BackBit Chip Tester ups your game with vintage computer diagnosis and repair. Tired of playing a guessing game with swapping chips? Don’t want to risk putting bad chips in a good machine (and vice versa)? Want to do as little desoldering as possible? Then the BackBit Chip Tester is your solution.

If you don’t see the chip you want tested here, it can be added!!!
I will add a test for any chip that I have in my possession. If a part is easily available, I will source it, otherwise if you could let me borrow a working chip that would be helpful. Send an email to backbitio@gmail.com with what you would like tested.

  1. David Ziegler (verified owner)

    Got mine today!! Serial number 17!! Looks to be a fantastic piece of kit! Seems to be quality everywhere on this device! Did some test and the results are proper. What a fantastic device!! Thanks for creating this! Now I just need to get some test clips and test that piece.
    Thanks So Much Evie, you are awesome!!

  2. Dan Goswick (verified owner)

    Got Serial number 1! I really like the quality and effort put into this product Evie. Great job! I’m excited about the potential to add many more chips from other systems. It would be cool if there was an easy way for us end users to set up test scripts. Nice work!

  3. Raj W (verified owner)

    Serial number 62 (so close to 64! haha!) Very easy to setup and makes chip testing a breeze! The results are clear and accurate. Thank you for making this Evie!

  4. Dean Jenkins (verified owner)

    Serial number 277. Evie releases firmware updates roughly once a week with support for more ICs and improvements to testcases. I am keen to use the tester to test the chips in my non-working Commodore 64 (breadbin) which died about 30 years ago! I have tried several times in the past to fix my C64. Now I have the tool to make my diagnostics more effective. Thanks.

  5. Stu (verified owner)

    Awesome, just awesome!
    A solidly built device!
    Fast to learn and easy to use.
    Was testing chips within a few seconds after reading the well written manual!
    Easy to understand the well thought out interface and controls.
    Fantastic!

  6. Albert van Bemmelen (verified owner)

    Thanks Evie for this remarkable and very nicely build tester! (my Pro Chiptester build number #284). You are making any retro repair and testing those IC’s especially for Commodore and also standard CMOS/TTL chips a breeze! You even included the well known 555 and 556 chips and also FDC controllers that probably no other tester for this affordable price tests! Hope that many more new free upgrades will expand this already magnificent Pro tester in the near future. Hopefully also for the Commodore Amiga computers.

  7. Brien King

    This is an excellent device. I like it so much I made a stand for it.

    #482 arrived in the UK this week!
    What an awesome well built device.

    Thanks Evie, this has already made my retro restoration journey much easier.

  9. David H

    Arrived in the UK on 31st March 🙂

    The tester has been invaluable for going through a pile of BBC Micro and RML 380Z board pulls, weeding out a few dodgy ICs – my goodness, this has saved me a whole heap of time.

    I’m now going through Unilab Three-Chip-Plus board spares and noticed there isn’t a 4047 IC (monostable) in the database. How does one get a new IC defined? I’m likely to come across other weird and wonderful 4000/7400 ICs. The BBC Micro has weird high speed memory buffers 81LS95 no other buffer IC seems to share the pin out.

    • BackBit

      Thanks, you can post on the BackBit Forum (forum.backbit.io) with requests for chips to be added.

  10. John M (verified owner)

    In my opinion the Chip Tester Pro v2 is the best IC tester on the market. I also believe it to be the best supported with an active forum and quick updates. There were 6 updates in August 2023 and so far in September 2023, there have been 3 and today is 9/12. No other tester I have adds features this quickly. It is also the only one I have that can test registered PAL, timer (555, 556, 558) IC’s and CPU chips. If you are on the fence just buy this one. It is great for reading and testing chips.

  11. Cyberjobe

    Fantastic.

    This tester receives a daily update of the supported ics, which makes it a truly great product. I really hope to see support for RAM 2101, CPU 6502A, 65c816 and eprom 2708. Is it hoped to be able to write eprom and prom in the future with a special update?

    I’ve had my CTP V2 for over a week and it’s saved my bacon! I was able to diagnose a bad bank of RAM chips in an IBM PC/XT and sort through other RAM on hand. I’ve been testing a big batch of 7475 chips I have. And I verified a XT-IDE ROM as good and backed it up to microSD. Money well spent, I’ll be using this quite a bit.

  13. gottjoe (verified owner)

    I received mine yesterday, and started testing suspect chips for my Commodore computers today. I find the tester very easy to use, and it provides reliable and accurate testing results for my needs. The additional feature of being able to rip a ROM is going to be helpful with my projects I work on as a source of learning. I have yet to explore other available features that are included in this device. Great job, Evie!

  14. fredwalter086@gmail.com (verified owner)

    Ich habe mir auch den Chiptester Pro V2 gekauft.
    Die Lieferung erfolgte nach Deutschland sehr schnell und unkompliziert. Ich bin sehr beeindruckt von dem Chiptester.
    TL071, 072, 074 werden wohl nicht mehr unterstützt schade.

    I received my Chip Tester Pro serial #1414 after only 5 days of delivery time from California to Denmark including customs handling.
    Works great and the update to the new main v4 firmware was a snap. Tested the WD1770 chip from a old disk extention board in my Acorn BBC B Micro and it tested OK after being in hybernation for almost 40 years.
    Evie is doing a fantastic job supporting her innovative gear, so both thums up from me!!

  16. Starbase Alpha LLC (verified owner)

    This has quickly become our go-to IC tester, as we work on classic arcade PC boards. Love the knob that allows to quickly step through the menu, as well as the “burn-in” repeated test mode.

  17. Qubert (verified owner)

    I very rarely leave reviews but I have to on this one. The Chip Tester Pro V2 is such a fantastic piece of hardware. The selection of chips that can be tested is amazing and in my extensive use it has been perfect in detecting faulty chips. This tool has saved me hours of frustration (and most of my hair) when a board build doesn’t work. I simply test all chips before I put them on the board and haven’t had a miss yet. Thanks so much for making this!!!

  18. Romain

    Thanks for this amazing tester!

  19. Richard Murphy (verified owner)

    If you’re into vintage computers, this is an amazing piece of hardware that will save you a ton of time. It is constantly updated and improved…money well spent!!!

  20. Aaron J Climas

    I have been borrowing $1058 from a friend here and it helped me get an Apple ][ working in no time at all because not only did it tell me what ics were bad, but what *gates* didn’t work.

    The ease of use of this tool, plus all the extra functionality such as ripping ROM, proms, GALS just make it the bees knees.

    I’d highly recommend getting the RAM tester add on boards.

    The only *minor* complaint is if you’re jumping between testing say a 74LS00 then a 74LS245 it can take a while to scroll down. So it’s certainly worth organising your ICs and testing in batches.

  21. Patrice (verified owner)

    The CT Pro V2 is a very accomplished and efficient tester and the extent of component testing is impressive.
    The affordable price is an additional advantage, as well as the great responsiveness of Evie for updates to this product with a major advantage concerning the specific requests made by users of this tester carried out in record time.
    A must-have tester!

  22. Gareth (verified owner)

    Awesome piece of kit!

    My life has been so much easier since it arrived retro restoration has never been so much fun.
