Alpha Electronics Dynamic Integrated Digital IC Tester on eBay
I chatted with the seller and he confirms that it does NOT power up. So chances are the battery backed up system ROM has failed. Item 390623172259 He reduced the price on his own from the original asking $59.95 to $19.95. Pity. I was hoping to find a good one to extract the program from to save mine... If someone here buys it and CAN extract the ROM data I'd sure like a copy!

Really a very interesting device!I was looking for a similar tester able to doing TTL in-circuit but I'm arrived too late..:) Is there any chance to get another one or a similar device? I can swap my B&K Precision 550 and 552 models logic comparator for an in-circuit tester.

OK, John, tomorrow I will do the scans (there are also schematics) ad I will e-mail to you. Regarding TTL in-circuit testing, since I repair arcade PCBs for job , I'm looking for a good and reliable tester which can point me in right direction at least (logic comparators are not very reliable IMHO). Yes, obviously best thing would be to test TTL manually with the truth tables and a logic probe, but , let's say, you have no schematics of the PCB and dozens of other board that are waiting you..:) ----- Original Message ----- From: "John Robertson" <jrr@flippers.com> To: <techtoolslist@flippers.com> Sent: Tuesday, July 09, 2013 10:47 PM Subject: Re: [Techtoolslist] Alpha Electronics Dynamic Integrated Digital ICTester on eBay

If these are CPU controlled boards then you may want to consider investing in the Fluke 9010 or 9100 series CPU exercisers - you will need an assortment of CPU pods too of course. Can get expensive, but the "Learn" function can tell you a fair bit about the memory layout of the board. Mind you these tools are mostly for 8 bit and only a few 16 bit CPUs from the 80s. Not a lot of use on modern boards. John :-#)#

Thanks Jon.I have already a Fluke 9010 and a Z80, 6502,8080 and 68000 POD but I find it useful only for testing RAM and ROM.Sure, it can point you in right direction (you can for example, identify bad buffer or addressing decoders) but it can test single TTL. I hav also three logic comparators but , as I said, they give a lot of false positives. That tester from Alpha Electronics was very intersting but , sadly, it's gone. There is the ABI BOARDMASTER 4000 but it's very rare and expensive... ----- Original Message ----- From: "John Robertson" <jrr@flippers.com> To: <techtoolslist@flippers.com> Sent: Tuesday, July 09, 2013 11:09 PM Subject: Re: [Techtoolslist] Alpha Electronics Dynamic Integrated Digital ICTester on eBay

You must be doing something wrong then, the HP 10529A is your best friend. Don't think that a good in-circuit tester is going to tell you anything different to a comparator. In fact, in-circuit IC testing is less comprehensive than comparison, because a comparator actually takes account of the circuit hook-up, where an in-circuit tester has problems with tied/forced lines, conflicts and busses. In-circuit testing cannot help you find faults that are to do with dry joints/cut tracks/speed issues, good though they are.

Hi Andrew. Yes, I have an HP 10529A as well as a BK Precison 550 (TTL9 and a 552 (CMOS) but as, I said, I don't find them 100% reliable.

I have a HP 10529A, ICT-101, BK-560 and BK-552, Fluke 9010A and one 150Mhz Tek Scope. As many others said, I used the Fluke 9010A to troubleshoot Address, Data Bus and ROM checksums. When some board's region where found suspect, I use BK-560 or ICT-101 to find some obvious problem in TTLs and RAMs (in case of using BK-560) and them I use the HP 10529A. Based on my personal experience, in-circuit IC tester will tell you if one IC is good (in most cases), but a bad reading is not necessarily a bad IC. This is where the HP 10529A in conjunction with a logic probe and a logic pulser can help. I use all that stuff when a board schematics is not available - very common in brazilian boards (local Taito versions i.e. Galaxian - Fantastic, Time Fighter - Time Pilot, Olympic Games - Olimpiadas, PacMan, Donkey Kong Defender, etc...).

Hi Jose. Is it true that you have to disable any clock while testing TTL in-circuit with B&K Precision 560? Is ICT-101 the famous Board-Walker? In conclusion, did you find this B&K Precision 560 useful (I have chance of getting one at reasonable price)? A scope is what I'm missing now! P.S.

Hi Fabrizio, I use to remove the Processor before testing, but as far as I remember it is not mandatory for BK-560 but it's recommended for ICT-101. I don't know if ICT-101 is the famous Board-Walker, someone else told me that, but I'm not sure. I like BK-560 because it tests 2114 and many other RAM types in-circuit, ICT-101 is easier to use and more practical, but less reliable them BK, I mean, it set as undefined/bad more ICs them BK-560 - as I said it not necessarily a bad IC. If you have one BK-560 for reasonable price, I would suggest you to buy, but consider to get one HP 10529A as well. Unfortunately I don't have it's PC software, but I think it's more useful to automatize the troubleshoot process when you have to fix the same board type many times. Will check the firmware version.

Hi Josè and thanks for explanation. Telling the truth, I have already three logic comparators :).I have -HP 10529A logic comparator -B&K Precision 552 CMOS Tester(like the your..by the way do you use it also for TTL testing?) -B&K Precision 552 TTL Tester But, I found logic comparators not very reliable, a lot of time they report an IC as BAD while it's good and for it's very boring to desolder and resolder a lot of ICs So, I want to try this B&K Precision 560.Last question: I know that there are problems when an input of a TTL is hard-wired to GROUND or VCC, also in the B&K 560 manual there is mentioned of this issue. Did you ever experienced this and how did you overcome it? ----- Original Message ----- From: "Jose Luiz Martins" <joseluizmartins@gmail.com> To: "Technical Tools Mail List" <techtoolslist@flippers.com> Sent: Wednesday, July 10, 2013 11:30 PM Subject: Re: [Techtoolslist] Alpha Electronics Dynamic Integrated Digital ICTester on eBay
Hi Fabrizio,
I use to remove the Processor before testing, but as far as I remember it is not mandatory for BK-560 but it's recommended for ICT-101.
I don't know if ICT-101 is the famous Board-Walker, someone else told me that, but I'm not sure.
I like BK-560 because it tests 2114 and many other RAM types in-circuit, ICT-101 is easier to use and more practical, but less reliable them BK, I mean, it set as undefined/bad more ICs them BK-560 - as I said it not necessarily a bad IC.
If you have one BK-560 for reasonable price, I would suggest you to buy, but consider to get one HP 10529A as well.
Unfortunately I don't have it's PC software, but I think it's more useful to automatize the troubleshoot process when you have to fix the same board type many times.
Will check the firmware version.

Hi Jose. Is it true that you have to disable any clock while testing TTL in-circuit with B&K Precision 560? Is ICT-101 the famous Board-Walker? In conclusion, did you find this B&K Precision 560 useful (I have chance of getting one at reasonable price)? A scope is what I'm missing now!
P.S. What software revision mount your IC tester 560?Did you have also the pc-side software for RS232 communication?

I have a HP 10529A, ICT-101, BK-560 and BK-552, Fluke 9010A and one 150Mhz Tek Scope.
As many others said, I used the Fluke 9010A to troubleshoot Address, Data Bus and ROM checksums.
When some board's region where found suspect, I use BK-560 or ICT-101 to find some obvious problem in TTLs and RAMs (in case of using BK-560) and them I use the HP 10529A.
Based on my personal experience, in-circuit IC tester will tell you if one IC is good (in most cases), but a bad reading is not necessarily a bad IC. This is where the HP 10529A in conjunction with a logic probe and a logic pulser can help.
I use all that stuff when a board schematics is not available - very common in brazilian boards (local Taito versions i.e. Galaxian - Fantastic, Time Fighter - Time Pilot, Olympic Games - Olimpiadas, PacMan, Donkey Kong Defender, etc...).
But in most cases, the scope is my best friend.

Hi Andrew. Yes, I have an HP 10529A as well as a BK Precison 550 (TTL9 and a 552 (CMOS) but as, I said, I don't find them 100% reliable. I'm thinking about a B&K Precision 560 like this:

OK, John, tomorrow I will do the scans (there are also schematics) ad I will e-mail to you. Regarding TTL in-circuit testing, since I repair arcade PCBs for job , I'm looking for a good and reliable tester which can point me in right direction at least (logic comparators are not very reliable IMHO).
You must be doing something wrong then, the HP 10529A is your best friend. Don't think that a good in-circuit tester is going to tell you anything different to a comparator. In fact, in-circuit IC testing is less comprehensive than comparison, because a comparator actually takes account of the circuit hook-up, where an in-circuit tester has problems with tied/forced lines, conflicts and busses.
In-circuit testing cannot help you find faults that are to do with dry joints/cut tracks/speed issues, good though they are.

Hi Group, I couldn't help myself. I figured at $19.95, this would be a cool little device to have even if it doesn't work. Get it in the mail, read the documentation that came with it and couldn't find a battery. Hmm, that's odd. But there is a power jack. And everything looks brand new, not even dust! Pop it open, no battery but a funny thing what looks like to be a RAM stacked on something else, a few custon chips, etc. No standard EPROMs that I could dump, bummer. kids are in bed, back to the schematic and it'll take between 9 and 12VAC. Looked through my wall wart collection and found a 12VAC one. Wired it up, hit the switch and... COMMAND? scrolling across the screen! Figure i'll let it run for a half hour if there is a battery somewhere and it needs to be charged. My question to the group is, how do I dump the program on this thing?

It works???? Cool! This is a CMOS battery backed up RAM - it should be able to be read by a good eprom burner as a 27256. Heck read it as a 27512 to be absolutely sure of getting the correct memory size - it will just mirror the data if it is smaller. The battery is under the cover on the thick IC with the warning label on it. Do NOT remove the battery until you are sure you have valid data. The way to be sure is to send me the file and I'll drop it in one of my chips and test my unit. John :-#)# On 07/16/2013 4:26 PM, Default wrote:

Update to TTL:
Tom tried reading the data and was unsuccessful and since then the device won't boot - so he sent it to me, I then tried reading the DS-1230 with my Xeltek and got what appears to be a fair bit of reasonable data. My earlier read of my DS-1230 got a some of what also looks like it may be valid data so I'm hoping that these two files can be merged to produce a working image.
Not that I have any time though to do this.
Anyone here familiar enough with Z80 code interested in looking at the two files and see if anything can be done?
I'm putting the two files on the FTP site so folks can take a look-see...

He reduced the price on his own from the original asking $59.95 to $19.95.
Pity. I was hoping to find a good one to extract the program from to save mine...
If someone here buys it and CAN extract the ROM data I'd sure like a copy!

Many moons ago I accidentally erased the code from one of these Dyna IC testers, but another unit has finally shown up on eBay and I have an active bid on it. My plan is to archive the good code after first verifying that I can read and write to the old unit (the blown one) with some random code. The current eBay one appears to still be alive!

Tom tried reading the data and was unsuccessful and since then the device won't boot - so he sent it to me, I then tried reading the DS-1230 with my Xeltek and got what appears to be a fair bit of reasonable data. My earlier read of my DS-1230 got a some of what also looks like it may be valid data so I'm hoping that these two files can be merged to produce a working image.
Not that I have any time though to do this.
Anyone here familiar enough with Z80 code interested in looking at the two files and see if anything can be done?
I'm putting the two files on the FTP site so folks can take a look-see...
