Well the ACA500 is going to suprise alot of people.
It suprised me, been testing it for little under a day now and its like using an A1200. Speed is awesome and all the features, you are really spoiled. Makes me want to have an A500 again just to play with one. The boot menu is cool, so many options, you can even boot with no physical KS ROM in socket, very cool. It brings the A500 up to the standard of an A1200 (minus AGA), no null cables, just jam in your FAT CF card and transfer your files, as you would with a A600 and A1200.

hi fol. was that just the aca500 or did it have a another aca12xx card plugged in? oh,any chance you could put up a sysinfo benchmark with raw transfer speeds,mips etc aca on its own and with a aca12xx of your choice when youve got a sec.i know its not tottaly acurate but its just to see in general.

Professional slacker!

@Roy ACA1220 needs a fix to work with the ACA500, Jens has said he will apply this for anyone that needs it done (just raise a ticket on his site)

I thought it was PIO0 like Gayle?
If it is PIO0, then the theoretical maximum would be 3.3MB/s and 2.4-2.5MB/s is as much as you can ever get in real life, even with a 060. And for some reason, I get lower speed with PFS3 on Gayle on my 1200. With FFS it is around 2.4MB/s, with SFS around 2.2MB/s and for PFS3 it is 1.9-2MB/s. |

Sysinfo speed test reads direct from device driver. Filesystem can't and won't have any effect.

Yes, you wrote that earlier, but apparently Sysinfo wasn't told about it as the difference is consistent on my 1200. After making an image, I repartitioned my SFS formatted CF card to PFS with similar sized partitions, and copied the entire contents over to the new partitions. Thus, the software is the same. What else would cause this difference?

Only change filesystem of existing partition and reformat it and I will guarantee speed won't change. Boot from floppy disk that only has sysinfo. |

I have to agree, I have only ever seen speed increase when using an accelerator.

FOL,
please remember that you have a debug-software in that ACA500, which sends out information over serial. Not sure what log level is set for that version, but you might want to use some higher quality cards to get closer to the 4MB/s limit that can be reached with Sandisk Extreme III for example. Jens |

ACA500 will also get a "bigger brother": A version for the A2000 with IDE port and separated CF card slot, which has an additional circuit to support hot-plugging for a lot more CF cards.
That funny spoke on the card is meant for protection against inserting it reversed. It'll push against the front case if you try to insert it the wrong way round, keeping you from pushing it in. Also, the 34-pin cable that connects the CF card adapter (meant to be installed in place of the second disk drive) has reverse-polarity tolerance: The computer will start up fine, nothing will break, but some software will be able to tell you that the cable should be connected the other way round.
