I need some help from some of the Guru's on here! My parallel ports quit today, its weird, neither the gvp I/O or my amiga parallel ports work no more. I can print to a fax and I can print to the printer thru the same cables from a laptop but not from the amiga, it just sends the wrong characters and it seems the linefeeds and carriage returns are missing, from pagestream it looks normal it sends and sends and completes but the printer never ejects te page so U take it off line and form feed it and all i get is either a blank page or one line of crap. I swapped the 8520 chips and it still does same thing (swapped the 2 on the motherboard to see if problem changed). I have also done a restore from tape from a time wwhen I knew it worked and booted from a floppy. It also seems I cant mpount rad disk anymore either. The Machine is a 2000 with a GVP 030/33 board with 16 megs of ram, a picassoII board, 3 harddrives a DAT and a scsi scanner. I have made no changes to the OS except to add CDROM drivers last month and it worked since then. All ideas welcomed!!! Thanks Keith Shook on AutoPilot!
