What is Optima 32 v2.0?

Optima/32 v2.0 (Requires 68020/PMMU or 68030)
Allows access to 32 MB of application RAM memory.

  • OPTIMA 2.0.0 can run on any Mac II class machine, regardless if it was manufactured with "32-bit clean" ROMs.
  • OPTIMA normally requires System 6.0.7, and only functions as a RAM disk under System 7. On the IIci only, it can be made to work with Systems 6.0.4-6.0.7. Foreign Systems (including Kanji) can run with 6.0.6 and 6.0.7, but 6.0.7 is recommended.
  • When operating in 32-bit mode, ALL of the INITs, cdevs, and programs that you run must be 32-bit clean. Currently, MultiFinder is not 32-bit clean, and as a result, only operation from under Finder is available. NuBus cards which contain their own INITs in ROM must also have 32-bit clean versions.
  • If your machine hangs on booting, before you can get to the Control Panel to turn OPTIMA off, •••boot while holding down the ESCape key•••, or from a different system floppy. This will present a dialog box allowing you to switch back to 24-bit mode. 
  • If you are using MAXIMA with OPTIMA, you must install MAXIMA first, restart, and only then turn OPTIMA on. Before you de-install or drag MAXIMA out of your System Folder, OPTIMA must be turned off, and then the machine restarted.
  • NUMEROUS programs and INITs are NOT 32-bit clean.
  • It is suggested you start from a minimum (absolutely essential) System set, and add INITs in small numbers. There are so many revs of so many INITs, that it is often faster to test the ones you have rather than checking an exhaustive compatibility list which may already be out of date.

Compatibility notes

Not compatible with MultiFinder nor Desktop Manager.

Fixes in OPTIMA version 2.0.0:
Adds 32-bit capability to the original Mac II, IIx, IIcx and SE/30.
Please note that the hardware of the Mac II and IIx require special SIMMs.
Large SIMMs (4 or 16 MB) on a Mac II should be placed in bank 'B'.
The Kanji INIT has been fixed, and tested under System 6.0.7.

How to make Optima v2.0 work with OS 6.0.8
Optima 2.0 can be made to work with OS 6.0.8 by a very simple hack to the OS 6.0.8 Finder.
Use ResEdit 2.1.3 to edit the Finder.
Open the Finder's "vers" resource ID #1.
Change the Version number: from 6.1.8 to 6.1.7.
Change the Short version string: from 6.1.8 to 6.1.7.
Do File Save (Command S).
Close all ResEdit windows.
Quit ResEdit.

Emulating this? It could probably run under: Basilisk II
