A4000 memory and video output
« on: February 08, 2007, 09:59:02 PM »
I just opened my "new" 4000 to re-install the CV64/3D and try to get it working again, and unfortunately found a big problem. All my SIMM sockets where filled, and the machine shows 4Mb FAST, so I assumed they were 1MB SIMMS... Well, they are not - they are all 4MB SIMMs... Looks like only one in bank 0 works, as I tested every combination, and the other banks are dead... Does this mean that I need to put in new sockets, or could it be one of the ICs that is busted? There isn't really any battery damage that I can see...

Another problem is that the video output looks less sharp than my good old A2000. All letters have a bit of red shadow to it, etc. Is this something that is normal for AGA machines, or adjustable, or can I replace a capacitor or two, or a major pain in the a$$?

And finally, does anybody know of a place in the USA that is reputable and can fix that kind of stuff, or should I send it to Amiga France, and how do I get in contact with the guy in France?
