Hello there my fellow AmiBayers
Recently I put up for sale a 512KB A500 Upgrade -
If plugged into a Basic A500+ it adds it to the CHIP ram (giving 1.5MB CHIP), however if plugged into a basic A500 it would add the 512KB as OTHER ram, thus leaving the precious CHIP ram at 512KB =(
Well we cannot have this so here is a modification that you can do at home with just a craft knife, two track cuts and a soldering iron.
Skills Required
1. Ability to handle a *sharp* craft knife
2. Basic multi-meter use *continuity mode*
3. Ability to solder one point
First Notice
This (HOW TO) is based on a Rev6a A500 motherboard, with an 8372a Agnus, If I find an older board I will do a how-to as well.
Second Notice
If you perform these alterations it is on your OWN ONUS; that means if kill the A500, you hurt yourself or others,or blow-up the street its YOUR FAULT, you do this on your OWN responsiblity
This disclaimer includes but is not limmited by you wanting or having the urge to sing anything by "Barbra Streisand", "Wham" or "Miami Sound Machine" has NOTHING to do with me.
Now, with that in mind we can begin =)
