My life is manic right now. Not had a haircut in 6 months and just had work contracts extended for way longer than I wanted + others queuing up for other contracts... mad.

As soon as i can find the time to get some TF534 gerbers cut i'll do it. I need to make sure you guys dont get cup holders made from them though.. thats whats holding me back.

Thanks for the reply and info Stephen,

The lack of haircut tells me that you've definitely got your priorities right!

Cheers.

Update: I'm leaning towards cancelling the TF534 entirely for various reasons. There will be a board to replace it but its not going to be available until Q2 2019 i dont think.

Any chance I could get a few PCBs for my own projects? Personally I am a fan of the 534.

I have changed my mind again. I spent yesterday looking at what the next 500 board would be.. and its not something i can get my head round in terms of layout easily.. A BIG change is needed to put SDRAM on the TF534 and to make it clock switch.

So I'll push on and see if i can figure out this bus grant stuff.

My only planned changes for the TF534 at this stage are to wire up A7, A9, A10 and A11.

OK update.

I have fixed the Atari ST bus grant issue (i think).

I also have sorted a few things that i think will cause issues on the A2000. Pull up on BG20. As well as that I have cleaned up the board dramatically and ditched the pretense at dual 2 and 4 layer. Its now a 4 layer board.

I've wired up the missing address lines to the RAM CPLD and generally cleaned up the board. An order has been placed with JLCPCBs. Slow postage for cheapness and so it doesnt arrive at the same time as the TF330.

Same as the TF330 i'll post out boards each to Victor and AlenPPC when it arrives.
