Yep, you have right picture in your mind. GALs are cheap (22V10 is about
USD 3 here) and you can put a lot of SSI and MSI logic in this chip. I am
not sure, but I also think that isp versions are flash (reprogrammable).
There is free version of DOS equation compiler. So, the only thing you need
is a programmer. I did not yet received the Lattice CD, but from their web
page, it seems that their isp22V10 is simply programmable by 5 pins.
I also got the link to some web page, where is the schematic for a simple
programmer. I will try to build one.
