Atari STE v1 BOOSTER ic2 burned

[valfac]

Now I have one resistor of 470R and a capacitor. I understand that I need remplace the resitor for another with a value of 68R and desolder the cap, is correct it?

On the other hand, yes I have sim with 9 ics, then I should desolder the parity ic..

Internal blitter machine needs mods to booster...

Correct.

Yes, Parity simms malfunction in STE's.

Capacitor retired and resistor changed for a SMD 100R (less value I have in SMS 0805), and now the Blitter works well!

Official diagnostic cartridge Blitter test is PASS!

Now is time of desolder the ram parity,s ic.

Thanks for your great help! @exxos

Congratulations! That's a nicely performed step by step implementation of likely solutions resulting in success
