Re: North Star Parallel Port. ACCORDING TO MY LIFEBOAT MANUAL, THERE IS A PARALLEL PRINTER DRIVER ALREADY INCLUDED IN THEIR CPM THAT WORKS FINE (I TRIED IT). YOU'LL HAVE TO FIND WHERE THE PROPER OFFSETS ARE FOR YOUR INSTALLATION OF CPM. These addresses are the distribution offsets. right now HLIST points to a jump to the serial port: 5A09 C3525A HLIST JMP HOROUT1 ; Right Serial Port my address is FA09 for 56K CPM. the address for HOROUT1 is 5A5D. To get the parallel to work you point to error in above line... HOROUT1 is at 5A52 (FA52) HOROUT2 (parallel) is at 5A5D (FA5D). All I did was patch location FA0A to 5D and then ran: A>SAVEUSER Saveuser is the Lifeboat user area patch program. This works for the Horizon, I hope you don't have an Advantage. Bob Wood
