68k Accelerators, FPUs and other CPUs

Over the years I have been lucky enough to pick up some 68k systems that that had accelerators installed: two MacPlus machines with Novy Quik30 Plus accelerators and a SE FDHD with a Mobius 030 SE accelerator. As I dug around the internet looking for information I found a lot of of advertisements, reviews, and some manuals and drivers for various accelerators, I also found some contact names that I used to track down old employees through LinkedIn (with some success), so I decided to create this post to track what companies I’ve found information about. I plan to list all companies that made 68k accelerators and PowerPC accelerators for 68k machines, with the list linking to additional pages that provide details of the company and their products as I have time.

The first mention I found for an accelerators for 68k systems appear in MacWorld August 1986 with reviews of products by Novy, Quesse and LevCO, if you are aware of an earlier product please let me know.

I have found information on accelerators or logic board upgrades from the following companies: apple,

Logic board upgrades and addon cards by Apple

Apple

Apple mainly offered upgrades in the form of new logic boards for their systems, e.g. when the 512 was released you could swap out the 128’s logic board with the 512’s, etc. For now I’ve limited the list to an upgrade in the CPU.

Applied Engineering

In fall of 1991 Siclone Sales and Engineering when bankrupt and Applied Engineering took over their product line (MacWorld 1991.08) and in early

Siclone Sales and Engineering Corp. (1988 to 1991)

Located at 1169 Borregas Ave. Sunnyvale, CA 94089 (MW 1989.03). In fall of 1991 Siclone Sales and Engineering went bankrupt and Applied Engineering took over their product line (MacWorld 1991.08)

MacProducts USA

    • Added, I put it under SuperMac. SuperMac bought Levco in 1987, and all the reviews I`ve found refer to it as the SuperMac SpeedCard. I’m still adding to this list as I have time. There seems to be a lot of instances where one company bought another, or licensed from another. E.g. a lot of companies seem to have licensed tech from Novy, or simply re-branded a Novy accelerator as their own. E.g. Daystar selling the Novy Mac20Mx.

    Share driver for the Mobius 30?

    • I’m using the 4.99 Mobius driver, and Compact Virtual 3.02. I plan to post an entry on my site soon for how I have this all setup on my SE sometime this winter (way to many outdoor chores at the moment). Note: You can only use up to System 7.1.3 with Compact Virtual 3.02. System 7.5.x is NOT supported. Lack of support for System 7.5.x was an issue for pretty much all of these old accelerators. That said, you can use the Mobius accelerator on the SE under 7.5.5, you will get the CPU bump (or at least I did), but will not have access to the extra memory. I need to do some more tests to see what memory is being used, the 4MB on the MB, or the first 4MB on the accelerator.
