I am currently toying with the idea of designing a Zorro card for the Amiga. What would the interest be in a card with the following: 10/100 mbit Ethernet, 2 X High speed serial ports, 1 X ECP/EPP parallel port & IrDa? There is some preliminary information on my website

I am also looking at the possibility of adding a Zorro to ISA bridge and making the card work in Zorro 2 and Zorro 3 Amigas.

Are there any other features you would like?

If you are interested, please email me. If there is enough interest I will look at making some prototypes and if feasible, a short production run.

Ethernet100 with USB2 would be great... an UDMA IDE and clockports would come handy too. An IDE interface seems quite easy to add (even if it doesn't autoboot or has dma it would be useful) Take a look at the A500IDE project in Aminet. I say usb2 because if you use zorro3 it would allow the use of higher speeds (in contrast with the clockport usb interfaces, which only allow you to use slow speeds)
I think that a card with UDMA IDE, Ethernet100 and USB2 would be interesting even for those who have PCIs because these cards only have few pcis and that would free some slots. I wouldn't like to waste pcis in a usb2 interface for example. Let's say you buy a MediatorZ3/Prometheus and you plug Voodoo3, a TV card, a SoundCard and you want to add a g3/g4 accelerator (a normal SharkPPC) you will not be able to add an ethernet100, ide, dvd card, symbios scsi, usb card... if you free pci slots it always helps.
You also talk about an isa-zorro bridge... it would be nice, but the price should be quite cheap due to compete with pci interfaces. I think that it should include something that cannot be plugged in a isa slot to make it interesting. Maybe usb? autoboot ide? IrDA?
Or maybe making an all-in-one zorro2/3 card with:
-usb2 (slow speed mode for zorro2)
-isa bridge (with dma support it would help to use isa soundcards)
-ethernet 100 (10Mb/s for zorro2, I know ethernet 10 isa are available but it's still better than nothing and maybe it may make use of dma and the isa cards not)
-autoboot udma ide ports (slow speed for zorro2 but still useable)
-IrDA
-A1200 compatible clockports
For the isa bridge:
-If you remove the ide ports would it be too hard to autoboot from the multi I/O cards?
-The multi I/O card may be fitted in one of the isa slots.
-A sound card like 16/vibra/AWE32/64 isa may be fitted in one of the isa slots.
-Graphic cards... erm they are slow (as zorro2) but if the card allowed overclocking the isa bus it would give easily 9mb/s in Zorro3 (like a Pixel64). Making a graphic driver would be difficult, finding the right svga card wouldn't be very easy.
-make an isa.library/device or something similar to code drivers...
the second option if you go zorro2 only would be an ultra cheap isa bridge with IrDA, USB2 and some A1200 clockports. There should be drivers for Ethernet 10, multiIO (including ide, if it autobooted it would be great) and sound cards.
I say ultracheap because if you take out the udma ide ports and the ethernet100 it will not be much special.
If you go zorro3 and decide to take out the isa bridge you should include the serial and parallel ports.
