Interesting, so it uses the expansion port rather than sitting ontop the old 68000 socket..
I have one of them old Blizzard Turbo mem cards that fit internally.. Gives me 14 or is it 16MHz 68000 + 2MB FastRAM. But no IDE. Ballpark figure: How long before its done? |

NMI and Action Replay III possibility would be fantastic
![]() (in cooperation with the original author) Did you try with scsi.device modded kickstart 1.3 ? |

Spidi,
your sync design gets every single cycle, that's excellent. From what I can see on the pictures, you should have the possibility to add a MapROM function, this will give you quite some extra speed on Sysinfo stones and IDE performance (unless you run a patched scsi.device that's already in fastmem - then you already have the best speed). At this point, the ACA500plus (which is async, so loses a cycle here and there) beats your sync design just because of MapROM at 14MHz. You can beat the ACA500plus at 14MHz if you implement MapROM. However, you won't reach the ACA500plus speed if it's clocked at 21MHz or more :-) Jens |

Signman,
I didn't mean to hijack this thread, but to give Spidi some hints on how he can improve performance. I expect to have ACA500plus news early december. Please stay on topic here - it's Spidi's thread. Jens |
