[Forum] Any interest in Zorro cards? | ANN.lu |
Posted on 16-Dec-2001 01:32 GMT by Ian Stedman | 147 comments View flat View list |
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.

I can easily implement a DMA controller in VHDL. I've done similar things before.

I've interfaced 100 mbit Ethernet to a CPU without DMA but it is slow.
The main bottleneck is the Zorro III bus, realisable speeds are only 12-14 mbytes/second.
100 Mbit Ethernet would use 12.5 mbyte/second.

I know of 4 solutions. On my website I state that I will be using the SMSC 91C111,
an all in one 10/100 ethernet chip.
Bye,
