Also includes one serial port and one parallel port. The parallel port can actually be programmed to act like a normal Amiga parallel port or it can be programmed to act like a PC parallel port. You can not mix and match simms sizes on this card.
This card always tries to configure 32bit memory as a higher priority than 16bit memory whatever configuration you have. It is auto-configuring, however all 4 SIMM sockets should be filled and jumper 22 closed to allow the 040 to work in burst mode.
