Here's a little something I discovered recently, while debugging a Lucas
68020/881 board. You can now run it WITHOUT the 68881 installed. Just connect 
a jumper between DSACK1 and CS lines on the 68881. DSACK1 is pin K4 and CS is 
pin J3 on the 881. You can also jumper pins 7 and 15 of PAL U7 as an 
alternative. THis works 100% O.K. with the system and setcpu finding the 68020
and not the 68881. Of course you can'd run code with inline 'F' instructions,
but you CAN have the 68020 without buying the 881. I will be building a Francis board soon, so will find out if this works O.K. with it too. I don't see why noth though.               <<<Doug>>>
