English Amiga Board - View Single Post - Purchased an ACA500 (not plus) any downsides?

True what fitzsteve says here. I have a regular ACA 500 and it does not have enough RAM for most whdload needs. I have paired mine with a ACA 1221 A1200 accelerator. This works really good. I think you could buy some A1200 memory expansions instead of accelerator with RAM and that could work aswell. Just make sure to research for compatability before you buy. I think I read something about some of these memory cards not working with ACA 500/500 Plus.

Also, like Fitzsteve said, if running stock ACA 500 you could try to save 512KB by not using maprom. However, if you have an Amiga 500 and would like to run classic workbench or something that needs Kickstart 3.1 then instead of loading the built in kickstart to ROM you could buy a physical Kickstart 3.1 chip to save those 512KB. This would enable you to run whdload games that uses 1 or 2 floppies I think.

I never really messed around much with the stock ACA 500. I have uses it with an ACA 1233 and ACA 1221 (not the EC version) which has been working really good.

Another option could be something like this and select the 2MB option https://amigastore.eu/en/710-amiga-5...nsion-rtc.html

I think it should work. If you pair this with a real kick 3.1 that should give you some available RAM for whdload

Actually, this A1200 8MB memory card does list A1200/ACA 500 or ACA 500 Plus under features. So should work. So this seems like a much nicer option for you VS the above mentioned https://amigastore.eu/en/698-amiga-1...expansion.html

Also, if you have A500 Rev 6A motherboard or newer, and 512KB slow RAM in the trapdoor you can select the option in the ACA 500 menu to turn trapdoor mem into chip RAM. Giving you 1MB Chip RAM which is needed for most whdload games. If you have a Rev 5 board you need a new Agnus (8372A) to take advantage of this feature. If you have Amiga 500 plus then it has 1MB chip as standard.
