and that's with the DMA removed yes?

Okay, so it looks to me like the Glue is causing the system to halt. So check over your RAM,ROM, MMU and GLUE connections, I suspect it's something on the two SMT chips. Have you got a microscope you can view them up close with?

I'm willing to bet there are either very small bridges or some pins are not correctly soldered.

p.s. you can put the DMA back in now.

@alienkidmj12 have you made sure you have the links fitted on IC9 pin 10 and 11 near the cart port and the link on the 3V3 BUS IO PORT #2 on the middle two pins of the 4 pins inside the 68K footprint? I can not see them on your photos.

EDIT: It might be worth removing the PSU and posting a picture of the whole board so we can check for any other items.

Keyboards solder jumper is not done.

Also have you done the jumper link under the flashy clock port?

Apologies, for some reason I thought you had SMT GLUE and MMU.

Looks to be no link on the DS1315 socket. You must link pins 10 and 11 if not fitting the chip

i have socketed glue and mmu chips

i will fit this ds1315 later today, so that will prevent it powering on ?

i will do the keyboard solder too, top and middle i think is needed

i have joined the 2 middle solder joints already for flashing clock port

I can't remember but I believe not doing the jumpers on the DS1315 will stop it booting.

You can boot without a keyboard connected, so that's not stopping it.

Also what version rom are you trying to boot?

i have https://www.exxosforum.co.uk/atari/store2/#0054

so i have tried hi and low (1.04 and 2.06)

i have trudie as a tos decoder which will fit later
