A500 OCS to ECS
Hi all,
I currently have an A500 and am hoping to upgrade to ECS. The current Agnus is the 1MB 8372A 318069, and Denise is the 8362. I believe that the 1MB Agnus does not need to be changed (although changing it for the adapter with the 2MB Agnus is definitely going to happen at some point), but I believe that Denise needs to be changed to the Super Denise 8373 R4 390433-0. Does anyone have any suggestions where to source the Super Denise ROM for the A500, are there any reliable suppliers that anyone would vouch for? Once ECS is done, and my Gotek order gets here, the intention is to then shell out (within the next month or two) for an ACA500+, what kind of pricing is reasonable for those? Thank you in advance ! EDIT: Almost forgot... Any recommendations for memory cards for ACA500+ ? Are there any pitfalls I should watch out for |

As for memory cards for the ACA500+ I use the Sandisk Ultra 8GB CF cards and they seem to work well for me. |

Why do you need Super Denise? Super Denise features are almost useless. (It is fine if you only want it because you can )

That's why I got it; the new modes were nice on the WB - except four colors not...

I have a 500 with:
Agnus: 8372A / 318069-02 Denise: 8362R8 - but I have a 8373R4 ready to install. Gary: 5719 Paula: 8364R7 ROM :3.1 v40.63 Rev 6A motherboard. I have an A501 - so I plan to do the JP2 & JP7 mod to make it all 1mb ChipRam. I also have a TF536. Do I have the correct kit to ECS my 500? The board states `512k/1M RAM`, where only 4 of 8 slots are populated. If I was to buy more Ram of the same, what mods (if any) would I have to make it 1mb internal ? OR just do the JP2/7 mod, to use the A501 as additional ChipMem ? |

Jumper mod - if you really need 1MB Chip. Then a fast mem addition would be nice...I think some games woud benefit of some Fast Ram.

I also have a 1.5mb upgrade that has a gary mod board. It's almost as old as the amiga though!
If I were to use that instead of the 0.5mb a501, could I get 2mb fast/chip mem? |

Not so trivial to get a rev 6 to 2MB by utilizing a large trapdoor expansion.
It is possible with an A3000 2MB Agnus, which is mostly pin compatible with the A500 Agnus. Jens is apparently working on an adapter board that converts an A600 Agnus to be A3000 compatible. However I would recommend finding a megachip board instead. |

I went the Megachip way. Supraturbo, then Apollo 520. (and tower + Blizzard2060...)

These are 2MB A600 Agnuses. The pinout is subtly different to the A500/B2000/3000 and will need a carrier board.
