Complexity of Afterburner and additional features: I completely agree. The idea of programmable VPP though would still use MT3608 module, but this time it would be used to supply like...

Sadly, mt3608 datasheet states: " The MT3608 has internal soft start to limit the amount of input current at startup and to also limit the amount of overshoot on the...

I tried 220uF (electrolytic) before the switch and it did not eliminate the big dip. It does help to smooth the voltage. Here is my result. 

@artgodwin I re-read your report about your Lattice 20V8A. I checked GALep's definition for that specific GAL. The VPP they use is 12V. So either the PES data as read...

I've committed the hex file for you.

Thanks for the interesting report. I checked Aliexpress and I can't find any Lattice branded GAL20V8B ICs for sale. They have some unbranded GAL20V8B ICs. When searching ebay.com I could...

I've checked the original source code and schematic from GALBlast and it does support GAL20V8B. Also, ATFBlast mentions this: "GAL20V8 requires a socket adapter to remap the pins.". So in...

@ismal Could you please share the original JED file that you programmed the GAL20V8B on TL866II? I would like to check whether Afterburner could produce correct/idetical JED file when reading...

thanks for the source JED, it proves the afterburner could read the data correctly (same CRC found in JED as the original), but can not write at the right CFG...

I managed to program Lattice GAL20V8B with an adapter [see link](https://github.com/ole00/afterburner/raw/master/img/gal20v8_adapter.png) I made (based on GALBlast schematic). It looks like Afterburner supports Lattice GAL20V8B just fine without any source code...
