Amiga 500 mod to Amiga 500+

Chips was ok.
When i bought this Amiga sockets was already installed.
So with help of Amiga PCB explorer web page manage to found that pin 7 on U19 does not have proper connection so i used jumper wire to fix issues and it worked!!

I know this post is a few months old, but this week I had exact the same problem.

I also had pin7 of U19 without proper connection! Also had to use jumper wire to fix it... is that just a coincidence?

Hi,

I have the same board revision.
I'm wondering if this board supports Chip RAM expansion cards similarly to the full A500+ or what is needed for that?
Is the logic chip (U35) required so that expansions can be used to extend Chip RAM?

The reason I'm asking is I'm not that confident with my soldering skills so would like to minimize the soldering needed. Specifically if I can get by without soldering the extra RAM chips and end up with 1,5MB Chip using just an expansion that would be sufficient for my needs.

Thanks a lot!
