Issue with BetterWB

[Oldsmobile_Mike]

The only question I need to ask this...in the link it says it is motherboard revision 6 and up. Do I need to do any soldering? Is there someone out there can confirm if I need to do some wiring and soldering? If the answer is no, then I can just buy these chips without worry and do the upgrades easily...as long it is a matter of removing chips from socket and replacing them with better ones.

Which chip are you talking about?

Read pages 9-11 of this manual, it specifically mentions the Rev. 5 motherboard:

Even though you are not installing the Megachip (at this time), you will still need to do the required mods to convert your 512K on motherboard + 512K in trapdoor slot into 1MB of chip mem.  Oh, and also you will need an Agnus that supports 1MB.

I get the feeling you are kind of new at this.  For what reason(s) specifically do you want the additional chip memory?

Amiga's  are definitely fun "hardware hacking" platforms, and this is a very  common and easy mod.  Hence why there's different versions of it out  there.

Also have a look at pages 22-23 of the Amiga Release 2 Getting Started manual, available from here. It explains the ECS chips and the various part numbers of everything.

I need to increase the chip RAM to release me from the limit I will be facing with 512 KB. By having 1 or 2 MB is the best solution for me. When I have 2 MB CHIP RAM or even 1.5 MB CHIP RAM plus soon to own ACA1233 with 128 MB FAST RAM I will be able to have a very will functional and fun experience Amiga system

I will be able to programming in Amiga inside workbench comfortable. I will be able to view lots of icons or open more than one window without having out of chip RAM memory. I will be able to use OS 3.5 or even OS 3.9.

I will be able to use things like AmigaSYS or Amikit or these pre-package OS with ease and without difficulty.  But when things start to come to slicing and dicing in my motherboard that is when I say, I better send this to professional to do the installation.


I purchased the fat agnus but the problem I have is slicing and I do not have the tools to remove the original agnus or install the new agnus and do the necessary slicing or moding. Can someone here help me install it? Does anyone know if someone where I live can do the job for me?

All good reasons.  So you're not just using it for games.  

The Agnus chip just "pops" out.  You need a PLCC puller tool (also available on ebay, or any electronics supply place).  They can be tricky though, so as a backup Commodore "provided" two holes in the bottom of the socket, straight through the board.  In other words, you can remove the motherboard and just push the chip out from the bottom.

You didn't post your location so it would be hard for someone "where you live" to respond.    Worst case scenerio, send your system to someone like AmigaKit, they should be able to do the work.

I did email amigakit no problem. Oh no, I intend to use my A500 for all my personal Amiga needs..not just for games. My A500 will be used the same way as someone would use their A4000 for their daily tasks, except mine will be in A500 original keyboard case. This cannot be done in a 512 KB chip RAM.

For huge game usage including aga I have AmigaCD 32 and I intend to use CD 32 for games and for that reason. Better start collecting ISO images.
