@PaulJ : I stand corrected :) (I'm always happy to be wrong, it means I'm learning :) ).

Glad to see other programmer being able to JTAG these devices.
Working ones : MegaSTE (68020) / TT030 / Falcon with AB040 & Eclipse / 1040STF
Need testing : Falcon with CT2

I have no idea how long it will take to debug the odd faults though.
I would like to get one!
PCB with 68000 SEC assembled, nothing else.
I will do my tests with a Lattice CPLD, where I have all tools (compiler, programmer) available.
Unfortunately not pin compatible, so it will need some extra wiring..

I can send you a PCB.. but I think trying to force wire a different PLD would require much more effort than just creating a new PCB to fit your lattice PLD...

So using a stencil is a bad idea on the PLD then...

Onto the fun part... :roll:

Bit better results. I did solder a Videl on a Falcon last year this way without issues.

Is the clear stuff flux? I've not tried adding that to the inside, just solder paste but the needle for the paste is a bit too big, so I end up having to use desoldering braid to remove the extra.
If it ain't broke, test it to Destruction.

Yeah braid I use a lot of, and flux. I sent the last boosters off to be assembled for me as just can be doing without the hassle these days. I'm only doing this one myself as I got a bit of free time next week so want to see if I can diagnose the odd faults I keep seeing.

Well good luck then. Just ordered myself some Atmel Gals as my PAK still doesn't work and I know everything else on it does.

Hope you have better luck that I have so far.

Now to see if the PLD is found.. then onto doing some simple test firmware (pinout is different than last build so have to do some tweaked firmware :roll: )
