Why is it shown as being slower than a standard A4000 in the Sysinfo test?

Looks very cool. Similar idea to the old Xcaliber A3640 add-on. Hope the price is affordable compared to TF4060

I don't know the price of the TF4060. I do not sell ready-made cards .. only PCB with soldered rc elements and buffers costs 35 euro .. CPLD and memory chip have to be purchased on your own. |

Anyway. a cool project. for people with a 3640/3660 it can be useful.
but I want to warn you about the supporthell when people uses DMA stuff.... even if you tell "DMA not working" I can bet money on people will nag :-/ Anyway. kudos for the project! |

If you're using it for a DMA SCSI controller, Leave some motherboard RAM on, set it to less priority than the X-Calibur-type fast RAM. Then in the mount file for the SCSI partitions, set MASK to exclude addresses above the motherboard RAM. |

Just curious: Can you have a 3640 with your RAM mod with a 68060 stacked on top of that again?

But this RAM is not DMA'able so it shouldn't work anyway. Unless someone has used this RAM expansion with a Fastlane or an A4091 successfully. |

Have built this board, but RAM shows up only one or two times from ten ??
I've used Alliance and Micron type memory, swapped CPLD out but no luck |
