Ok, can you not do those with a tl866? They are just a gal equivalent right?

These chips are like 100pin using JTAG. Totally different programming tech than gals. You have to use the correct jtag programmer by atmel.

Is the Atmel programmer the same as for the atmega328 etc? As I have one of those somewhere

It needs to program the ATF15xx series..

Is it me? Or is there some kindofspider like faceless monster on the bottom one? Yeah, It all got hacked about that much it ended in a bit of a mess. TerribleFire will probably be having palpitations about it.... How many did you get made? Only 10. I can donate a board if anyone wants to build one ...

New PCB's arrived a few days ago. But due to intense man-flu, won't be any progress until next week.

Once I get this going, I can investigate these odd issues I have been seeing...

Well good luck, enjoy lots off time with your LA and scope then i guess? I don't exactly even have a LA... I do have USB one, but I already seem to spend more time fighting iffy software than doing anything. I have put in a request to TF for him to scope out stock timings exactly so I can see what ...

Sorry for the delay in getting back...

Its keyboards 1,2,3 in this post viewtopic.php?f=11&t=1308&start=20#p13544 which I still have.

Have you tried the 68R resistor ? You need to do all my suggestions first. I don't have much free time at the moment , so it could be several weeks before I would get chance to look at your board.

EDIT:

You still haven't posted a screenshot of the 16MHz signal as requested before.

just what I have been looking for.

Impressive you designed this whilst struck down with serious man flu

Took me a while but got there in the end. Not felt this bad for years

My old STFM 4MB SIMM adapter isn't being produced anymore. But I have designed the next gen adapter today which uses 2 SMT DRAMs instead. It's the same DRAM chips as I use on my 4MB MMU plug-in adapter kit, so it saves me having to stock some items and helps keep costs lower :) DSCF0052sm1.JPG 6.jpg...
