1550.0. "FDDI on PCMCIA or alternative?" by ONOIS1::GAIRNS () Mon Jan 09 1995 06:34

    We are proposing MULTIA X-Window terminals on a research vessel project
    (20 terminals mostly with infra-red remote control instead of a
    keyboard) to relay surveillance camera images.
    
    Because of the amount of data involved (MJPEG?), we require an FDDI network and
    image compression cards.
    
    The problem is that the MULTIA only has a single PCI slot and two
    PCMCIA slots.
    
    The PCI slot will be taken by the image decompression card so I only
    have PCMCIA slots for FDDI connections.
    
    DOES ANYBODY KNOW OF A PCMCIA FDDI CARD? (with Windows NT driver would
    be a bonus)
    
    Alternative suggestions such as:
    
    Fast ethernet - are a nightmare to our NIS men who are proposing DECHUB
    		    900s.
    
    2 or more ethernets per MULTIA are an architectural headache.
    
    ATM - PCMCIA ATM? and wot about the HUB 900s (We don't want to promote
    	  Chipcom).
    
    All positive remarks will be gratefully received.
    
    Thanks for your help

	>>DOES ANYBODY KNOW OF A PCMCIA FDDI CARD? (with Windows NT driver would >>be a bonus) I doubt it. We're the first to come out with PCI FDDI cards in both single-slot and mezzanine form factors. I couldn't even begin to imagine the mechanical work needed to design an FDDI controller into a PCMCIA form factor. It's an interesting idea, however, so if there are any HW engineers up to the challenge, let me know. :-) The only thing I can think of is to find out if there are any commercial PCI slot extension boards. This would be a board that plugs into the sole Multia PCI slot and provides multiple free PCI slots. The board would likely use a PCI-PCI bridge chip to support the extended slots. I don't know if there is anything like this commercially available. -Larry
