No, not at all. Probably it'd be wise to stick at the current speed for compatibility reasons.
My intention in talking about PCI/e was that once you pick up this task you should do the job thoroughly - without adding too much complexity, PCI soft cores are around.
Step 1: You could redo the Buster, maybe speeding it up a bit, but most of all removing the bugs.
Step 2: Integrating a PCI port opens the door for replacing the daughterboard with one carrying any mix of Z3, PCI or PCIe slots, connected to the Buster PCB by a ribbon cable. Better PCI performance without messing with Z3.
Step 3: The daughterboard has yet another connector for hooking up an accelerator board directly to the PCI world. Except for the Bvision port danbeaver mentioned all other solutions require the - fast - accelerator to go over the - slow - motherboard bus to reach a - fast - PCI busboard. Obvious where the bottleneck sits.
At the same time the '030-to-PCI bridge we built into Buster starts to work the other way around, interfacing the accelerator to the motherboard, removing some complexity from accelerator design.
Step 4: Why use an expensive and hard-to-get 68060 CPU? Better take a cheap, fast and cool(!) ARM CPU with integrated PCIe and 68k emulation in firmware. You won't see a difference except that it's faster. The 5V adaption problem has already been solved with the Buster replacement.
i agree in full. actually what we are talking about is a complete new pci busboard along with z3 slots for compatibility. this board might plug into buster socket, as i assume if we remove booster as it is now we remove the bottleneck. or perhaps is there any other good place to hook up? i mean, a socket or connector most of amiga boards provide, not just some of them or some of accel cards. also an arm accel with 68k emu is what i am advocating since ever, even if x86 might currently still be better choice because of jit.
