Thanks for the replies to my posting asking for 68881 add-on
info.  The machine I intend adding the coprocessor to is a
recent 1040STFM.  It has two ROM chips,  surface mounted GLUE
and MMU chips and the 68000 is positioned below the keyboard
space bar.  It has been upgraded to 2M ram.  I understood a
German company (Lischa Datentechnik,  Hochstrasse 22, 4173
Kerken 2) produced a board that was stuck ontop of the 68000,
it sounded suitable,  I wrote to them but no reply came.  If
any one knows about Lischa & the 68881 please elaborate. I
tried to get a Third Coast CMI accelerator board,  ordered it
in june,  they cashed the cheque,  they still havent sent the
board,  despite having advertised its existance for months.  I
phoned them, they said 'ready in two weeks' .....four weeks
ago.  I am not happy with Third Coast's service.
           In reply to Wolfgang Hecht's enquiry about ST
Fortrans,  the only Fortran I am familiar with is by Prospero.
It is well documented,  has a good debuger, and produces code
that runs 20KWhetstone/s double precision 50KWhetstones single
precision (and 200KWhetstones for both precisions with the
68881).  Both single and double precision use the IEEE floating
point format.  About the only gripe I have against it is the
rather slow compile and link times and the slow editor screen
manipulation (much improved with turbo ST 1.6).
