How come there are no support for eproms like 27c160/27c322 etc? I use them A LOT and I really need a new programmer.. but its kinda dealbreaker if it doesnt. Althou it can do alot of others but.. hmm
or ill just have to make smd to dip pcb adapters. wonder if there are any pinout availible for the ZIP socket if ppl would like to make own adapters?
Thanks!

Read my post #693. You can program a 27c160 by modifying the pinout and using a jumper for the extra address pins. (Btw 27c160 will never be directly supported as it has more pins than the programmer supports).
27c200,27c400,27c800 etc could be....
Personally i would like someone to write an addition to the tl866 firmware that allows for the programming to be handled by the host pc.
I.e so all the logic for driving and reading the pins is handled on the pc
I suspect that this may already be possible with the stock firmware for things like logic gate testing.
Unfortunately, that part of the protocol has not yet been reverse engineered or at least there is no mention of it in the https://github.com/vdudouyt/minipro code.
No, but I'm working on an Open Source Tester/Programmer. Since my last post on the subject I've done a ton of work getting a framework in place. Right now it's based on a PSoC 5LP which gives great flexibility in the dynamic pin mapping. In my latest tests, I was able to have it dynamically identify the exact failure mode of a 74LS90.
The nice thing about the way I'm designing this tester/programmer is that the data that describes each logic IC or eprom to be tested or programmed will be stored in a single plaintext file (one for each chip) in a human readable/writeable form. This will allow the user to easily add new chips. The file will be parsed and sent to the unit each time you hit the "Go" button in the software.

Issues with Atmel 28c16 (KM28c16-150).
This is the first time for me using an programmer and I run into a strange issue.
I purchased four KM28C16 eeproms to flash a new firmware (replacing old 27c16). I'm able to erase all four KM28C16 but when I try to program them only the even addresses are able to be written to, the odd addresses stay "FF" no matter how often I erase the eeprom. Selftest of the programmer show everything OK.
I use the latest version 6.17. I purchased the four KM28c16 together, now I'm confused if this is a tl866 issue or if really all four 28c16 suffer from the same issue and the likelehood of somehting like this
I also used my rigol to check the A0 address line and I can see that it is changing status during read/write operations.

Thank you very much I will give this a try when I got my new TL866 back, I send the old one back for exchange I know it is a shot in the dark but I keep you posted.
By the way I was able to program all four AT28C16 using a small batronix programmer no problem whatsoever so it is definitly the TL866 or the writing algorithm.
check your pin 21 it is not the same between the two vpp and WE ...
Yes you can change fuse settings using the TL866. Moreover, you don't have to worry about cocking them up like you do with ISP programming (e.g. reprogramming the RESET pin as an IO), because pulling the AVR and putting it in the ZIF socket means it will be parallel programmed.
Now I just need to figure out which of the checkboxes is the right one for Pin 14 (which theoretically is going to allow me to probe for frequency). Any suggestions on which one toggles 14?
And any safety tips on how to avoid bricking things? Thx
Check ur usb connection, make sure its on usb 2.0 not on usb 3.0...
