I would like to add a 68881 to my ST (to go with my prospero FORTRAN compiler). Is a reasonably priced add on board available, or has the necessary interface circuitry been published anywhere?. The board would probably have to bolt on to the 68000 as the glue chip in my machine is surface mounted. I noticed an odd effect when upgrading the RAM in my ST; it wont allow different sized RAM banks. Bank 0=500k,bank1=2M gives 1Mbyte total, bank 0=2M, bank1=500k gives an apparent 4M and a swift crash!.
