I tried posting htis earlier but didn't see it show up, so I musta hit preview and thought it was submitted...

I'd love to se a G3/G4 accelerator for my A4000T (Quikpak style) to put more life into it. Though I am going to have an AmigaOne as well. Perhaps an accelerator with a Megarray socket to share CPU module design with the AmigaOne...
A PCI bridge with an AGP slot (as well as Zorro and maybe one video slot if you want but I'd rather have PCI/AGP slots myself) that directly replaces the Zorro /ISA/Video slot riser cards in the desktop A3000/4000. One of the Mediators does this in A4000D, but not for my A3000D. :/ Then we could put the covers back on and use PCI cards without stuff sticking above the top of the machine preventing it from being closed up. And variations that fit original tower versions of A3000/4000 and something for A1200 users. I realize classics can't keep up with AGP speed, I'd just like functional use as AGP cards are more convenient to shop for and may offer more features than their PCI counterparts, such as the Radeon AllInWonder cards that include TV tuner/outputs not found on harder to find PCI Radeons.
And finally, a Buster replacement that could increase bus speeds beyond the available Buster 11 chips. A small FPGA board fitting intot he socket should be relatively easy to do, and SMT sockets can be fixed to boards currently having SMT Busters, making it possible to put the board in these machines as well as into socketed A3000 types. We could have more performance from aging machines this way and get faster PCI card accesses via the Amiga bus as well as fom Zorro3 native cards...
All designs with firmware ugradable FPGAs (SRAM FPGA with configuration EEPROM) to allow bug fixes and other enhancements via internet download and floppy disk program to re-burn the EEPROM/FLASH type thing, rather than sending board in for upgrading that can take a long time.
