ACA500 unpacking error 3?

TjLaZer · 02 October 2015, 19:10

Anyone else having intermittent unpacking error 3 when trying to start up their ACA500? I get this when I power on my A500 and press F1 or F2 to boot to Kickstart. If I reset the machine it goes away. Usually happens on a cold boot.

I was receiving these, and worse (green screens - both at boot-up and 10 minutes or so after finally booting up). I *think* it was related to my A1233 accelerator, for when I replaced it with my A1220 accelerator, all errors disappeared.

I cleaned the contact point with rubbing alcohol on both the ACA500 and A1233, and for a few days now have been running with the A1233 without any issues (boot-up or afterwards). Also, just to play it safe, I pulled the various chips, cleaned them, and firmly re-seated them.

I am NOT claiming to be an expert - I just wanted to share my experience.
