[munch a bunch of fr.....] Two questions or those in the know. 1) Why do the floppies for the amiga have 880K formatted capacities when so many others have 720K ? How about the 1.4M floppy drives (say by fujitsu) - can we install them and get 1.4M storage. 2) Where can I find the complete listing of ansi commands supported by the con: device? The Amigados manual only seems to have a subset - trying to work on a better termcap for uw don't ya know. Thanks. tim.

Conventional controllers have the ability to read and write single sectors at a time. This requires a certain amount of space be left between sectors. As the Amiga reads and writes entire tracks at a time, there is no need for these spaces and thus one can put more sectors on each track. I don't have the specs on the 1.4M floppies. If they simply double the number of tracks you can probably do it. If they instead double the bandwidth you can't do it with the built in floppy controller. >2) Where can I find the complete listing of ansi commands supported >by the con: device?

If you have access to a SUN termcap (which is ANSI), you could use that... -Matt

How about the 1.4M floppy drives (say > by fujitsu) - can we install them and get 1.4M storage. Because the Amiga squeezes sectors side by side on each track and get 11 512 byte sectors per track as opposed to 9 512K sectors ala MS-DOS. No 1.44 M drives will NOT work on an Amiga, they require a different Data clock rate. >2) Where can I find the complete listing of ansi commands supported >by the con: device?

They are described completely. Note that the console device may not be a full ANSI 3.64 implementation. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.
