After a long time, I finally I managed to get hold of a USB<->RS232 cable, which allowed me to hook my A1 to this machine.
I thought the CPU of my A1 got fried for the second time, but the keyboard lights gave some hopes... and, in fact, the serial output does show that the machine is alive! Still, there is some damage...

I'll try to take re-seat the chip, but I guess it will be pretty useless.
Any ideas anyone?
EDIT1: it seems it's not possible to send commands, neither by means of the keyboard, nor through the terminal. U-Boot seems stuck.
EDIT2: by pressing madly [ESC] and [ENTER] during boot, I managed to get to access to the prompt! The settings have partially gone - this is all there is:

EDIT3: I have fixed the settings and now the CRC error is gone, but the 0 kB FLASH and no VGA problems remain
