Based on GALBLAST by Manfred Winterhoff
http://www.armory.com/%7Erstevew/Public/Pgmrs/GAL/_ClikMe1st.htm
Based on GALmate by Yorck Thiele
https://www.ythiee.com/2021/06/06/galmate-hardware/
Supports:
* National GAL16V8
* Lattice GAL16V8A, GAL16V8B, GAL16V8D
* Lattice GAL22V10B
* Atmel ATF16V8B, ATF22V10B, ATF22V10CQZ
* Atmel ATF16V8B, ATF16V8C, ATF22V10B, ATF22V10CQZ
Requires:
* afterburner PC program to upload JED fuse map, erase, read etc.
