[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 have looked at the feasibility of using an SDRAM controller, which would allow
the use of DIMMS. I have the VHDL model I need for a controller but there are
some technical issues.
1) The current Zorro 3 bus is too slow, 12-15 mbyte/second. SDRAM can transfer
400-600 mbyte/second with overheads, from experience.
2) DIMMS have a 64 bit bus interface, the Zorro 3 bus is 32 bit, so I would need
a fast multiplexer and extra control logic for this.
3) The SDRAM controllers I have are designed for one memory type. I need to
be able to auto detect the DIMM type and configure accordingly. At the present
time, I do not know how to do this.
Relating to USB.
I am looking at this. I am in the process of learning about it and I hope to have a solution soon.
Bye,
Ian |
