ADLiPT

ADLiPT is a driver for the "AdLib on a parallel port" OPL2LPT board. For more information, see the thread on the Vogons forum.

Download

Download the driver from the Github releases tab.

Usage

EMM386 or QEMM

Load the TSR with the command:

ADLIPT

assuming the OPL2LPT board is plugged into LPT1. It will use about a kilobyte of RAM. It can be loaded into high memory using the DOS LH command.

The TSR can be unloaded with the command:

ADLIPT UNLOAD

JEMM

Load ADLiPT using the command:

JLOAD JADLIPT.DLL

Options

  • OPL3 Enable OPL3 support. Use this if you have an OPL3LPT.

  • LPT1/LPT2/LPT3 Select printer port.

  • BLASTER=220 Enable Sound Blaster FM emulation. ADLiPT will intercept the Sound Blaster FM ports in addition to the standard AdLib ports. (It won't however fake enough of a Sound Blaster to pass installation checks, so this won't be very useful if you don't have a Sound Blaster.)

  • NOPATCH Disable runtime patching. Without runtime patching the TSR will be much slower, but the I/O timing will be much more regular, which might help with software that's very timing sensitive.

System requirements

  • 386 CPU
  • A compatible memory manager:
    • EMM386 version 4.46 or later (tested with version 4.49 from MS-DOS 6.22)
    • QEMM 7.03 or later (tested with QEMM versions 7.03, 7.5, 8.0, 9.01)
    • JEMM 5.78

EMS memory is not required. If you don't use software that requires EMS memory, you can load EMM386 with the NOEMS parameter.

Source code

This program compiles with OpenWatcom, use the build.sh script. You'll also need Python 3 and the Ragel state machine compiler.
