A501 RAM expansion not working?
« on: August 08, 2014, 03:07:07 AM »
I thought I only had 512k of ram, but opening up the trapdoor, I found out that it had a A501 ram expansion. When I boot up the Amiga it shows the time (probably a dead clock, since it shows 1970's) while loading, but when I remove the ram expansion, it shows no time, but once I'm on the Workbench (1.3) it shows 371752 bites of free memory, or If I remove the card, it shows the same amount. Is it dead Jim? Should I buy another card, or is there a way to get the Amiga to recognize the card fully?

Should I buy another one, or are there better ram expansions for the A500?

I'll open the A501 later, right now I'm copying games to floppy for my Amiga. I want to be able to play games like Super Frog that require 1mb of ram. I don't want anything fancy or complicated to setup.

Thanks for the replies.

Edit again: What do you think about this or this? I want something that isn't going to have battery issues.


Edit: I got the shielding off with all my brother help.

Here are pictures of the ram. I see what looks like damage around the battery.

If you want a RTC and don't want to mess with soldering a replacement battery on, you might want to look for one that has the replaceable button battery on it.

Some trapdoor expansions have a soldered in rechargeable battery I think, but still, if the battery dies, you have to solder a replacement in or a battery holder for a new button style battery.

I'm sure others will have additional suggestions.

Maybe something like this: http://www.ebay.com/itm/311016244763

Will a standard 512k ram expansion be enough to play Super Frog and/or use Protracker?
