URL to buy one, maybe more? Found it, too much usefull i/o has
disappeared, so I'm not that interested. I am using all 4 usb jacks
+ spi at 40 megabit write and 25 megabit reads, but I suspect that
would crash and burn at much lower speeds with a cable to a 7i90
much longer than the inch I'm using. And I'm not willing to dedicate
the only wired ethernet port to a 7c80.
The 7C80 (and 7C81) are SPI interfaced devices
Thats much better Peter, but how long can the cable be?
It need not be longer than 1.5 inches or so since the RPI mounts on top of (and
get power from) the 7C80/7C81 via a 40 pin flat cable
