[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.

Any interest in Zorro cards? : Comment 49 of 147 | ANN.lu |
Posted by Ian Stedman on 16-Dec-2001 21:29 GMT | Taking a few comments onboard, here is my reply.
1) Cost. I need to get some manufacture costs but the 3 chips I need will
cost £40/$55. Connectors and other chips, another £5-10 ($7-$14).
2) Zorro2/3 compatibility. I am working on the interface design and within the
next month I should know what I can implement. I will investigate the Zorro 3
DMA issue.
3) USB. I am looking at this, using a Microcontroller I can probbly add USB.
4) Make a PCI card. I could not compete with any of the far east manufacturers on cost.
5) Clock ports. I have yet to find some timing information on this port. If I do, it is
feasible but unlikely.
6) Updated feature set. The information on my website needs an update. I am using a
single chip, PC Style 'Super IO'. This give the following:
2.88 Mbyte floppy (do these still exist?)
2 x 16C550 serial ports upto 430 KBaud + IrDa support,
ECP/EPP parallel port,
Standard mode IDE port.
All this in a $7 chip.
7) Zorro to ISA bridge.
The Super IO chip has an ISA interface so I will need to implement an ISA
controller, so I just buffer it for the ISA sockets in Zorro amigas.
8) Software. I wrote a working ethernet driver and IP stack in 2 weeks once
so this is not a problem. I am prepared to make the software source available.
In summary.
I will continue my research and intial development.
I realise I need a competitive price, I will have a good idea once I get some manufacturing quotes. |
