I will measure the voltages on each pin according to the link.
Once the PS works again I will try to get the parts needed for the crowbar.
l have a second PS like that so should build two crowbars then.
According to the self test almost all RAM is damaged maybe Basic ROM too as I cannot start with Basic anymore.
Computer starts directly with the memory test, keyboard is not working so I guess Pokey is dead to.
The PS failed while the computer was switched on but I didn’t see that Since I was away from it with the TV switched off.
when I came back I switched on the TV and power cycled the 130XE and only memory selftest since then.
I opened up the Atari and quite some ICs got very hot so I switched it off immediately. Have not switched it on yet again.
will do so once I find my SysCheck from tf_hh again.
I let you know my measuring results of LM723.
Thanks a lot so far for your help and input
