Adding 512 Chip ram to A500 Rev 6a MB

[Dropcheck]

Hi,

   So I've given up on my quest to transform a A1200PAL machine into a red,white and blue NTSC machine.  Silly me I thought it would make sense to make one mb and have a easy way to switch between video standards.   :crazy:

   Okay so my next quest is to upgrade the chip ram on my A500 Rev 6a mb.  It has the plated through holes for the additional memory dips, now solder covered.  My A501 card is working just fine.  Is there any other mods I need to make other than soldering the additional ram chips?

 :-?

Thanks,

Talking about A501 - you're not thinking about adding 512 MB chip RAM onboard with the A501 in place, are you? These two exclude each other since they use exactly the same signals.

Well..... I thought about it  :crazy: Nah, I know I need to remove the A501
