A bit of confusion about what is Parallel Printer port 1 maybe? The standard IO address of 3BC+ is for the parallel printer port on a Monochrome Adapter card. The "Printer Port" LPT1 has standard 378+ IO address. True, the standards for "first" printer port has 3BC+, but the standard for LPT1 is 378+.
