Did you get this ATX board from the guy making it in Poland ? Atari ST ATX gerbers can be found on http://ataripcb.pl/ and you can order your own PCB. If ordering the ATX PCBs, also order the RAM card as this is needed as well. I am not sure if x_angel has the updated PCBs on his site so just in ca...

Yes, these ATX boards were created by x_angel.

ATX board now has the PS2 socket fitted but I ordered the wrong PIC chips for the eifel code. I ordered PIC16F872 and they should have been PIC16F876. Have now ordered some PIC16F876 chips and have to wait for them to arrive as there are none local I can buy. Have also built up a second ATX board to...

Atari ST ATX board is mostly built now and it was powered up this morning... I am pleased to say it worked first time and TOS 2.06 booted up and showed 4mb RAM tested. TOS 1.04 also booted when jumpers were changed on the board. I am still waiting on the PIC chips for the Eiffel and also the PS2 con...

I am also missing issues 6 and 57 if anyone has issues 6, 45 or 57 and would like to scan/contribute/sell them, please contact me. I still need to work through sca...

Just to confirm, your video shows 10k RN11, would 4.7K work as I didn't order a 10K in my Mouser order?

Top components solder in place and beep tested the pins on the CPLD confirming no solder shorts between pins. Oscillator was too small but have managed to solder it in place.

Okay, here we go with my build progress... First up had to wait a bit longer for my OSHPark order as they missed the silkscreen on the first AfterDark run. New PCBs with silk screen arrived today. So I have 2 sets of PCBs now, some without silkscreen and some with. Will build one with silkscreen fir...

Audio comes from the Yamaha YM2149 chip on pins 3, 4 and 38 and is combined to create mono audio to the 13 pin video port.

You could always add this modification for stereo
