(512)891-3733 1200 baud. There is a file with this description: 68343ffp.arc Source code for the M68343 Fast Floating Point routines. . (Unsupported!) I suspect these will work for the 68340 as well, perhaps with minor modification. I have not downloaded this file, so I can't comment further. I just hoped to point you in the general direction. There are probably many other sources for M68000 floating point libraries. Chances are that you may find out where they are by asking on the Freeware BBS. -- Roger Chaplin / Instruments Division Engineering / "Though I'd been lost now I chaplin@keinstr.uucp / CI$: 76307,3506 / felt I was found when He #include / looked at me with His #include "disclaimer.h" /* cover all bases */ / forgiving eyes." - Michael Card
