Not sure if you have tried this supplier:

sunwenjun offers other kits with various adapters for the 866A and also for the 866CS
ymmv but sunwenjun has consistently answered my messages
I think the product and the support (not much has been needed) have been good
Hello
I use the TL866cs mainly to reprogram laptop bios chips. It seems to work well with older bios types, but the new ones with Intel Management Engine dont seem to work at all.
For example if I try to flash a new winbond 25Q64FVSIG chip with TL866 the laptop is completely dead and wont even turn on. This only occurs on never model laptops. Any idea why this is happening? Does the ME part of the bios somehow prevent the flashing prodecure from working? I use the default settings when flashing.
Anyone found a fix to the GAL22V10D issue ? I updated to 6.17 but that has made no difference. Also, re-installing the first version of the software didn't work as it doesn't seem to like the later firmware in the programmer. Any way to roll everything back ?
It certainly looks that way.
I sent some emails to guessed addresses (support@autoelectric.cn and sales@autoelectric.cn) the other day. I thought that I was in luck but they both bounced today.
To add insult to injury, I had thought about buying a Genius 540 but I don't know that I could rely on that working with the GAL22V10D either. It would also take a while for it to arrive. So, I ordered the connector, etc. and built one of these -

You can imagine my annoyance to find that the GALBLAT.EXE software doesn't run on my 64-bit Windows 10 machine As far as I can tell, it runs ok on my 32-bit Windows 8 netbook but that doesn't have a parallel port
So, really peeved at the moment
Hello guys ,
I just bought my TL866A , however when I try to read my 93c86 the overcurrent protection kicks in .
I've go through this pages and I've read to short the C22 . Can anyone please elaborate on how can I do that ?
Thank you

Are you trying to read the IC in circuit?
Ok some update ...
I short the C22 to disable the overcurrent check. Verify by checking on the self device test and it shows fail for overcurrent protection.
Now it can read the 93c86 EEPROM but the hex value is different everytime i clicked on READ .
Hmmmm ... I suspected this due to overcurrent?

Hmmmm ... I suspected this due to overcurrent?Actually more likely undercurrent (assuming you are powering the EEPROM with the target powered off) - you will be trying to power up all the ancillary circuits to the EEPROM from your TL866 which just can't cut it.
Are you using one of those in-circuit 8 pin clips? What you want to do is disable the VCC (tiny piece of tape or paper on the VCC pin - or just cut the wire and solder some jumper pins to reconnect them if needed). Then either rely on the target being powered on or providing an external VCC from a PSU.
If using the target then you may run into problems with the I2C lines being in use by the CPU - so you need to hold reset or some other work around.
Is there anything I can do with that to revive it?

Ahm you might try using radiomans sw updated/changer on this thread,
https://www.eevblog.com/forum/blog/eevblog-411-minipro-tl866-universal-programmer-review/375/
follow the instructions, click reflash, if theres no activity disconnect and reconnect the tl866.
Success!
Christmas is saved!!
