How does the programmer interface to the ATF15xx series ? must have JTAG cable?, as inserting the SMT TQFN package be near impossible into the programmer..

There a column that lists adaptors, I have some but haven't checked the the adaptor specified. It also burns the cplds for bf's boards but I'm going to use the Raspberry so I can check them after soldering as his video shows.

@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 can donate a board if anyone wants to build one up, but will need a Atmel programmer.
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.

Still didn't go perfect though...

Did a crappy short video..




Its going in the US to clean up next before I get sticky fingers!

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.
