Xgecu TL866II Plus vs T48 vs T56 

This is great info, mate, and I really appreciate the time you've taken to make a comprehensive review and rundown of EPROM programmers. I've got a few projects that are stalled because I don't have a programmer so have to bodge up Arduino and breadboard type fixes which quickly becomes all too much like hard work when taking ICs in and out of boards.

Very clear descriptions of the three units. This has been needed for a long time. Looks like the T48 will be ideal for automotive use. Thanks for taking the time to do this review.

This was the video I have been waiting for. I need one of these. !!

Awsome review. Well worth the time spent watching. Will be buying myself a T48

excellent review thank you! I have the TL866II+ and thinking of upgrading to the T48 exactly for that extra Vpp capability. As you say the software looks sketchy but it just works :)

Just got the T48 and it's great for retro hobby. No problem with 27xx ROMs and I really like the logic testing of 74xxx components. Thanks for the review!

A friend bought some cheap frequency counters for some test jigs he was making. One worked but two didn't. They used a PIC to do the counting and segment driving. I copied the PIC with my TL866II+ and re-programmed the PICs in the ones that didn't work. Thankfully, the copy-protection bits were not set. All of the counters worked after that. I haven't programmed an actual EPROM for decades, but I have programmed many other devices, and the logic chip testing facility has been useful for the diagnosis and repair of industrial logic boards. I don't think I could justify the additional cost of the T56, but it's good to know that there is the option, should the need arise.

This has been super helpful to this synth repair tech - thank you!!

Your review was so compaling that I order a T48 for only 48$! All the best.😊

Your video is amazing! I have one question, if you can. Regarding 1.8v bios using XGT48 is necessary use the adapter? Reading manual I'm not sure if is needed or they recognize chip and auto adjust tension. Thks and Rgds

Exactly the rundown I was after. I've been thinking about getting a programmer for a while now and at that time only the 866II+ was available, but with the new line out I think the T48 is where its at.

I appreciate the comparison of the three and guidance/suggestions in the video. I am buying my first and found the information very helpful. I know you mentioned it in the video but do you have a link and list for the software that is needed?

I also got T48 sometime ago and no complaints. I think it is very versatile and good quality piece for the price. I also haven’t recommended old TL866 programmers to anyone at this point because of the voltage limitations. I have programmed several old EPROMS that require 21V for programming and T48 manages them without any problems. XGPro software is also very good, it just works. Chip information is not always correct, though. For those eproms I mentioned, software default setting used 12V, if I remember correctly, which is not enough and programming failed. Datasheets may become handy, even though the chip selection in the software is impressive. It is quite nice that software also shows the correct adapter to use in the info tab after you selected the chip.

Awesome, useful video. I was kind of lost in the weeds before this. I used to have a Willem eprom programmer circa 20 years ago but after moving several times, I don't know where it is and beyond that the program would have probably been designed for Windows 2000. LOL The T48 looks perfect.

This video was a huge help thank you very much.

Thank you so much for this! I'm not s programmer, I experiment with oscillator circuits and old oscilloscopes just for fun. I also have a fluorescent mineral collection and recently learned about UV Eprom (versus double-e eeproms) and mainly wanted to read an eprom and test slow data degradation via various UV lamps I already own. On Amazon and eBay they have a ton of cheap "eprom" programmers that list only double-e eeprom chips as being supported. I found what I finally thought was a useable programmer and wanted to double check before ordering it. Turns out it was the middle one you recommended (great!). I'll order that and a quartz window chip to play with. I also have 5 large bins of old circuit boards with various chips I can play with. I did a similar thing with a cheapo data logger to see the logic pulses. Ended up diagnosing a bad wifi thermostat, lol. Anyway, this is just for fun but you really helped me out.

Is there any way to distinguish fake vs original form the lasting pictures before we buy?

Wow thank you for the awesome video

Great video!! I’m using a BATRONIX BX-48-II and it’s SW alone AND it’s superior autosensing looks much better than the SW of the Xgecu units. BATRONIX support is also amazing. IF there is a chip that is not supported, just call/email support and in 30 mins they update the chip database. Still, the fact that Xgecu units come with all these chip adapters is really great. With BATRONIX you have to buy those adapters separately.

One major thing I think you forgot to mention for the t56. It allows you to plug in an external power adapter for eproms that require higher voltages to program.

Thinking about getting the T56 the bigger zif socket would come in handy and the speeds, I do a lot of arcade PCB repairs and it can take a while to program a lot of eproms, my Tl866 has done very well though there isn't a lot it won't program I have to say, even now they still do firmware updates on the thing.

As an owner of a tl866A (with the side pins) with the 21V and it is awesome for cars/vehicles and ECU. But I might need to step up to t56 so I can reprogram all the newer chips on laptops, server motherboards, and other devices (other than cars/trucks/farm equipment). TL866 is also supported by open source linux software. I am surprised by the prices of the programmers; they're going up. I am researching the difference. Good video.

Hello, which programmer should I use to read the M29W256GL flash memory? Thank you

great review. subbed and liked. thanks a lot

I did buy the tl866II since i had to program an eprom. The software from the website works without problems under linux using wine.

Hello Sir, on the T 48 clip, how did you connect the color codes for the 4 pairs of wires running from the clip? I see number 1-4 then 5-8 on the chip i have for the T 48, but don't know which color goes where. White, Purple, Blue, Green then Red, Brown, Black, White I'm trying to extract the firmware from a WD external HDD. thank you in advance for any advice

I'm having difficulty downloading the installation and driver software from the Exgecu website. How did you do it? Thanks

I have the tl866a, and while i dont program or use it occasionally, it solved my laptop repairs few times, but my last job with an winbond 25r256 couldnt be fixed with this Unit. I hope with the t48 this wont be an issiue and it will be future proof for next few years

I got a great adapter for the T48 at 6 euros that connects to the socket and uses a ribbon cable to the 16pin header too, and with it I can program the 42 pin 27C322 and 27C160, without having to split the ROM in parta and flash in sections or anything. That 16 pin header seems to give you those pins you are missing from the 48 pin socket. Very handy for the old Sega Mega Drive and the 16bit microcomputers of the time.

Hola. Con el modelo t56 se pueden programar los chips ec o kbc de laptops?

is it possible to do chip of data recovery by these from ufs or emmc chip?

Has any manual for the T-48 appeared? Great video by the way!

I have missed a full programming cycle of some memories test, to grasp the speed increase in the t56, both in read and write.

Great review. I find myself needing to program some memory again, and the last time I did it was 20+ years ago. I dreaded the thought of having to dig out my old parallel port Neeham's unit and finding an old PC to run it on. The T48 looks like the ticket. Thanks!

Does the T48 support writing and reading OTPs?

Could someone please help clarify for me how to successfully "test clip" program a soldered Macronix MX25L4006E SOP8 and a Winbond W25Q128JV SOIC8 chip both on the same TYAN S5545AG2NR-HE "secure flash" model motherboard using this XGecu T56? I understand that this model needs custom "crossover" wiring from the ICSP to the clip and proper grounding and whatnot and the diagram which comes up in the XGecuPro Software v1266A for each module to explain the "in-circuit" custom ICSP pinout is not clear at all to me concerning how this test clip should be wired for a successful chip pin connection. I bought this for work for this particular time-pressing project I'm working on and cannot make heads or tails of how I'm supposed to wire this ICSP to test clip for these two model chips. This T56 is literally worthless to me if I cannot get this sorted out. My simple Coright Skypro is much easier to use than this device -- it literally autosenses all modules and senses with successful programming many SOIC/SOP-8/16 soldered "in-circuit" chips with POMONA or 3M Test Clips with little struggle. Admittedly my handy Magnifying Lamp is a huge help in getting solid clip commections and minimizing destroying clips too quickly, but this soldered Macronix MX25L4006E on the TYAN S5545AG2NR-HE "secure flash" model motherboard is not reading or writing correctly at all. I've ruined 3 total clips struggling before realizing the chip needs a custom wiring for a successful ICSP connection. The problem is what exactly that 8 pin wired schematic looks like. I've messaged the XGecu and posted on their message board with zero response. If you boast in-circuit programming concerning your programming product, you shouldn't make the instructions impossible to sort out. This is extremely frustrating. Can someone help me out with this "in-circuit 8-pin SOP pinout ICSP connector to Ponoma test clip" please? I also have a nearly unused TL866II Plus with SPI DRIVER ICSP Enhanced Adapter if that is easier to use for this task.

Hi, does the T48 support the "XGECU T56 SN-ADP-VGA HDMI/VGA Interface ISP/ICSP and Serial output support" or is this purely for the T56? Thanks

Can this T48 programmer work for stm32f and As15f IC? Please let someone help out thanks I need to know

I "thought" I brought a great deal on AliExpress for the T56 with adapters. Turns out it was a supporter pack (adapters-only!) - duh! So... may question is, I know you said as a general rule of thumb, don't mix adapters, but that was really aimed at the older/white programmer and the T48. Are the adapters for the T48/T56 interchangeable? i.e. Now I've seen your video - am I good to buy a T48 and still use the adapters I accidentally brought ? [UPDATE] I think those that use the zif socket will work. As it happens, I need a TSOP56 adapter (not got) and that seems to be unit dependent T48 or T56 ONLY as whichever version I get will use the port at the bottom with the pins (using a cable), and since the ports are very different - it makes those adapters which use the port, unit dependent.

Can the T48 and or T56 program ITE ENE Super IO's?

Please, may I know the difference between T48 and T56, please?

Hello! Thanks! Please advise, can I use adapters from set for TLL86 also and on T48 or T56 programmers ?

مرحبا اخى اواجه مشكله فى قرأة ناند رقم 29f64g08cbaba يعطى فى virefy error block ولا اعرف أين المشكلة علمآ انى اقرأه بواسطة t56 وشكرا للاطالة

Does anyone have a recommendation for a good eprom eraser? The ones on Amazon and eBay look like they are cheaply made clones of something. Also, is there a good source for 4/8/16k roms suitable for Atari cartridges? Thanks!!

From my understanding and research the 866ii is more for automotive EEPROM work which is what I own. The other two or more for TV repair and from my research (not personal use) you will not have the chip support for automotive EEPROM work out of the other two units.

Thanks!

How useful are the adapters that come with these? Are the adapters ones that folks would actually use or are they just thrown in to raise the price without really getting anything of value?

Which is better, t48 or t56? What are the main advantages of the t56 if it is 100$ more expensive than the t48?

Friend, which one is better? T56 T48 for only emmc

Благодарю за хороший обзор, много узнал нового и мой лайк. Просмотрел используя яндекс переводчик. Технический перевод достаточно понятен.

What programmer software do you use for T48??

I'm very surprised these aren't like $20 each. What makes these so expensive?

Can we program ec bios in tl866

*about the direction of the chip at the beginning

the T48 is better if you're not using Linux. Linux minipro supports the TL866II Plus. It doesn't support the T48/56

I still find it crazy you need a 70$ programmer to program >5V programmable ROMs... So I'm making a
