I would start with trying another computer, and another USB cable.

Thanks for the suggestions.

No dice on the different USB cable or computer, same Pin 4 GND error.

I'll wait until the seller replies and see what they want to do.  Sending it back to China would probably be half the value of it.  It is probably a simple repair, but I get antsy when desoldering gets involved, especially on boards with lots of SMD.

hi, how long does it usually take to erase an eprom (m27C4001)?  I bought a gray Chinese eraser like this one in the picture.  I have some m27512 eproms original that clear in 6 minutes.  instead the m27C4001 original are canceled in 40 minutes.  it's normal?  thanks

@galaxy76 --
What is wrong with the answer below, which you received earlier in resonse to pretty much the same question?
Also, could you please delete two of the three redundant posts you just made? [Done, thanks!]

i bought a chinese eprom erase 4w 254nm (grey) .  I have to delete some Chinese eprom m27C4001.  how many minutes does it take?  thanks
For a good eprom, 10 to 15 minutes should about do it. I've used several thousand M27C801 Chinese eproms and on the rare occasion I've had to erase one they take 1-2 hours. They are branded ST but scrape off the black paint and they have some Chinese writing underneath.

From ST datasheet:

Quote
The recommended erasure procedure for the M27C4001 is exposure to short wave ultraviolet light which has wavelength of 2537 Å. The integrated dose (i.e. UV intensity x exposure time) for erasure should be a minimum of 15 W-sec/cm2. The erasure time with this dosage is approximately 15 to 20 minutes using an ultraviolet lamp with 12000 µW/cm2 power rating. The M27C4001 should be placed within 2.5 cm (1 inch) of the lamp tubes during the erasure

You can compare the requirements such as the wavelength and dosage against the ones for other UV Eproms.

Hello,

Sorry to revive a somehow old thread, but does any of you know if the TL866ii Plus can reliably test 6116 Ram ICs? I've heard people saying they do test them fine and others saying it doesnt.

I would only buy it for this purpose and thats why Id like to hear from someone who actually owns it if its a good tool for this purpose.

The 6116 is in the chip database for the TL866+ but have never tested these chips before.
I've tested loads of 62256 and those work, so dont see any reason why the 6116 would not work.

The problem is that TL866 will test chips in relative low speeds. I have tested several ICs with a pass result that would not work in the circuit, due to higher speed clocks.

The thing is, Im trying to repair an HP test equipment and this is the first time Im actually messing with these 'old' digital circuits. How does one actually confirm an IC is bad (like in your case) with such defects? I mean is it even common for for ICs to fail this way, working only at lower speeds?

I need to test a few 6116 ICs and that why I was interested in getting the TL866, so it would be great if someone could confirm if its suitable as a 6116 tester, if someone here ever used it to test them. I dont like the repair approach of just replacing everything as we dont learn much from doing that, so Id rather test and find the issue than just replace all ICs... and I love test gear as everyone around here so a GOOD IC tester would be awesome to have.

The TL866 and other affordable chip testers will be able to determine if a chips is definitely not working but can not determine if they are fully functional (meet all specifications). It is just not practical to fully simulate working conditions so they just test for basic functionality. So if a chip tests bad then it is very likely bad. If it tests good then it is still suspect.

These are primarily universal programmers and as mentioned the software works more like a basic pass/fail so it's a check not a test. Since this thread is for the TL866A/CS and not IC/RAM testers please start a new thread in the test equipment forum if you want to discuss testers further. But you are looking for something like this, not the TL866:

If you make a new topic, please post a link here. I am also interesting in SRAM testing. Speed is not the only issue in my case, these parts, like the 6116LP-3 and similar, were used in old music synthesizers for battery-backed settings. I have a couple of tubes of "not sure" SRAM parts.

Hi,
How to disable SDP on AT28C256 with programmer TL866II-Plus ?
Thanks for your help.

I have to read out a AM27C010 DIL32,

TL866II plus have it the list

When pressing Read in Xgpro version 10.90 win7 64bit it complains about Pin Detect Error small red X on all pins except 16 (Gnd) and 30 (NC)

it also complain about wrong ID.

When deselect pindetect and ID check and the read it does read but all FF ( I know the Eprom does work and have content)

If run a self check all is fine

If I put a data pin to gnd (without Eprom) and read it sowhe the right Hex data for the gnded pin

So what's wrong?

I'm very late to this party but I found this topic by accident.
Earlier this year I bought after some advice from another topic a TL866A @ EvilBay - not knowing that this programmer is out of production for more than 3 years
and that there was the risk of counterfeit products.

Fortunately I got a NOS or very good counterfeit product and it has done the job I needed it for - reading out some old EPROMs with the last available software release after firmware successful upgrading and some reprogramming
of very old east german 2732. So far so good.

Than I tried to use it for reading out the code from a ANET A8 mainboard, I got the 3D printer used for less money but have no access to the used firmware.
Now I have to replace the main board (a analog input of the AT1284p seems to be dead) and I tried to dump it with the programmers ICSP port. The
board has a dedicated ICSP port! I double and tripple checked the cabling.
I bridged C22 to overcome the current protection warning but it doesn't work. After trying everything what I learned from this long topic I have to confess that I'm lost.

To get the hex dump for further reprogramming I bought a cheap 3€ USBasp programmer and with AVRDUDE (& AVRDUDESS - I prefer GUIs) the job was done in 5 minutes!

The USBasp stick powers the main board processor what is easy to see.

It assume that the TL866A  ICSP_Vcc supply doesn't work (yes - I crossed the field in the software). But I tried the printers PSU without the Vcc cable with the TL866A with no success as well.

Has someone experience with this kind of problem? Thanks for any advice!

Since you suspect it's a power issue have you confirmed this?

You can check if you have an original or clone here, unlikely it being original.
http://www.autoelectric.cn/EN/note.html

Let us know the hardware and software version you are using. What does the software identify the programmer as? Have you performed the CS to A mod on it?

Take screenshots of the software screen before you read and show the results/errors after clicking the read icon. This will help let people know exactly what is occurring.

Re. AM27C010 DIL32,

As I wrote I can't read it in the 866II+,

I took a scope and did measure the Vdd and it goes to 5V when the menu are set for read 5.0 V so far so good.

But if you measure on all the address pins the only swing between 0 and 3.3 V
The data pins swings between 2.5 and 5V (so it's never going real low)

If I change the menu to lets says read at 3.3V Vdd changes fine to 3.3V
The data pins swings between 0.8 and 3.3V  (so it's never going real low) AM27C010 is a 5V device

I had expected that the address pin had same swing depending as the Vdd and not just 0 - 3.3 always
The output might have the problem with wrong pull-up.

Any sugestions?

Reading some 27C256 and 27C512 (Fairchild)  I have around does work correct in the 866II+
So when I assume the 27C010 is a OK chip it might not be even though I see it work in the CPU board were it belongs to.
Will investigate a bit more

Hi radioman,
I just reflashed my TL866CS to ver.A. I get Reset error, during the last step. 
I can read from an earlier flashed eprom, when I deslect "Check ID".
I cloned my dev. code and ser.num. On this pic shows that it is ver. A, but ICSP connector not present.
How can I solve this?

If it won't go into boot mode you need to use a resistor to force boot mode by plugging the TL866 in with a 100-200 ohm resistor present then remove it once it's entered boot mode. Flash then it should boot back into normal mode. After that updating the firmware should be fine. The .pdf file (that comes with the updater) shows where the resistor should be connected.
