Power Macintosh 6100 DOS Compatible De-turbo Tool

I wrote a simple tool for the Apple DOS Compatible card for PowerMacintosh 6100. It allows you to enable/disable Turbo mode and adjust the de-turbo speed and disable cache to run software that doesn't run on a 486.

I tested it with Monkey Island EGA, Loom EGA and LucasFilm Night Shift, none of which run on a 486 66Mhz while using Adlib sound. All are working with this tool.

It should work on any 486 board with a CHIPS 84032 and 84035 chipset. Tested in MAME/MESS with AMI BIOS clone 486/66 Mhz and on a genuine Apple DOS Compatible card.

Source and binary are on Bitbucket.

  1. Hello. I realize this message probably won't reach you, but I just thought I'd try anyway.

    I'm trying to rip models from Virtual-On MARZ for PS2, with very limited success. I understand you have a couple of tools that could help out a lot.

    Not trying to be rude or anything, but I'm going to need:
    1.) Your tool that can convert PS2 PVR files to TGA files (the dropbox link no longer works), and
    2.) Your loader tool (from SANiK's notes) that supports Ninja Texture Lists(NJTL) and properly support GBIX IDs and PVPL palette swapping. (assuming you've worked on it still since 2011).

    Please reply back as soon as possible.

    1. I haven't touched it since and it was never really correct to begin with. Good luck.
