GAL programming - verifying what you're about to program

@exxos @Icky Good morning all. I'm after a bit of your sagely advice please.

I'm about to program a GAL for a different IDE adapter for the Mega bus, and rather than having a JED file, I have two blocks of text, one a GAL file and one that Ibelieve is a JED listing. I've attached both.

Is it simply a matter of removing the .txt extension from the JED file and using that, or would it make more sense to assemble the GAL file and use the resulting JED?

I'd be appreciative of your advice as this is getting a bit towards the edge of my GAL experience and I'd like to expand my knowledge a bit. I read that WinCupl can assemble GAL giles, but still trying to work out how to drive it.

Thanks in advance.

I would rename the JED.TXT to .JED and just see if your programmer accepts it.

I translated the code into a 22V10 for WinCUPL and put the LS03 in the GAL as well, but I never got it to work. The only reason that TTL chip is there is because the 16V8 doesn't have "open collector" outputs.. the 22V10 does. Amazing really after all this time nobody has updated the circuit in the same way.

@exxos Awesome, thanks very much, I'll give that a go. It is much as I thought it would be, but I had a wobble, hence the ask, thanks for the quick reply.

@exxos Seems to have programmed OK, will see what happens later!
