Nice article, a couple things i think worth mentioning, 8mb ram allows WHDLoad games to load completely into ram and allow faster access between levels etc, With an extra 512k chipmem added to the internal expansion slot you have a very nice WHDLoad machine,
This is a good point. Having used my ACA500 with an ACA1232 for a couple of months now I have to say it is not an ideal WHDLoad machine.
The ACA500 only comes with 2MB of RAM, and you lose half of this if you use maprom to boot Kickstart 3.1.
This is not enough for most WHDload games or demos. Most fail to run, the ones that do will have a blank screen while loading.
While you can install an A1200 accelerator into the ACA500, there is a performance penalty for anything that uses the Amiga chipset extensively. Unfortunately this includes most games and demos. I have found many of these will stutter and the music will slow down when an A1200 accelerator is installed.
This isn't related to whdload, even booting the games/demos off a floppy shows the same symptoms. With the A1200 accelerator removed however, everything is normal.
For Workbench and stuff that doesn't use the chipset, my ACA500 + ACA1232 flies. For WHDload, I'm finding more and more games/demos that don't work properly unless I to disable the ACA1232, and then fight to get enough free memory to run them.
While the ACA500 does have a few nifty features - external AUX CF card slot is great for getting files onto the system, KS1.3 + 3.1 with patched IDE and FAT support, and of course the A1200 accelerator slot which was no doubt quite a technical achievement - the lack of RAM and hobbled A1200 accelerator make this a disappointing WHDLoad solution for me.
If WHDload isn't your priority then the ACA500 is probably ideal. Otherwise I'd say one of kipper2k's boards is the better solution.
