Last updated on July 11, 2025
Over the years I have been lucky enough to pick up some 68k systems that that had accelerators installed: two MacPlus machines with 68030 accelerators (unlabeled, possibly Novy Quik30), a SE FDHD with a Mobius 030 SE accelerator, and a collection of NewLife Accelerators. As I dug around the internet looking for information I have 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.
Background
The first mention I found of an accelerator was an advertisement in MacWorld January 1986 for the Human Touch Computer Products Corp’s Three to One Touch Board that adds a new 68000 CPU running at 12MHz and up to 3.5MB of RAM., the next was an advertisement in MacWorld March 1986 for General Computer Company’s (GCC) HyperDrive 2000, that adds 1.5MB of RAM, a 20MB hard drive, a new 68000 CPU running at 12MHz, and a 68881 FPU, after that additional accelerators for 68k systems appeared in MacWorld August 1986 with reviews of products by Novy, Quesse and LevCO, if you are aware of any earlier products please let me know.
I created the following lists to summarize and link to the information I’ve found about different accelerators. I am in the process of adding images (when I can find them) to help myself, and others, identify unbranded accelerators (like the 2 I have for my MacPlus). I decided to group the information by the CPU on the accelerator, with subgroups for the supported systems. You may notice several accelerators with different names that look identical, this is often because the design layout was either determined by how the accelerator could “fit” in the system (the NewLife accelerator for the Classic is a good example), or the accelerator was sold under different names as a result of licensing agreements (e.g. from Novy and Quesse to Total System Integrations) or due to the sale of one company to another (e.g. MicroMac’s purchase of the rights to several DiiMO, Dove, Harris, and Mobius accelerators in the 90s).
Issues with 680×0 accelerators running System 7.5.x or newer
When Apple introduced System 7.5.x it changed how Memory Management worked, this change was incompatible with many of the accelerators, limiting the majority of accelerators to running system 7.1.x or 6.0.x with only a few venders making the effort to provide support 7.5.x, that change combined with Apples move to the PPC CPU’s killed the 680×0 accelerator market.
We’re sorry, but DayStar discontinued manufacturing 030/040/601 upgrades effective Fall of 1996. Effective September 1, 1997 DayStar is no longer able to offer any warranty or tech support for the 030/040/601 upgrades due to limited availability of parts and qualified 030/040/601 support staff.
DayStar 030/040/601 upgrades are only certified through System 7.5.1. While you may have limited success running with later System Software, we cannot support your upgrade. The later Systems have introduced problems which disable upgrade compatibility in many cases. Apple has also changed its policy of 100% downgradable compatibility. This decision and the resulting incompatibilities are the primary reasons DayStar discontinued the 030/040/601 upgrade product lines.

Modern Reproductions
Several of the accelerators listed on this page have been reverse engineered by Bolle and Zigzagjoe from the 68kMLA.org forum, and are occasionally offered for sale by them or others on the 68kMLA.org forum, or on ebay.

Drivers
I have linked some accelerators to sources for their drivers, but not all of them. When I have time I will go through the collections I drivers I have found: Macintosh Garden, Macintosh Repository Accelerator Card Drivers and Macintosh Drivers Museum Archive, PreterHuman (other/misc).
Note: Some drivers, such as the Gemstart Universal 7.1 driver, support multiple cards, if you haven’t found the driver for your specific card try a driver for a similar card, it may work. Also cards that only accelerate the CPU but do not add memory or other features may not need a driver to work. Additionally some cards also require Connectix Virtual or Compact Virtual to work properly.
68000 / 68HC000 Accelerators
These were early accelerators that either either 68000 CPUs running at a higher clock speed, or the newer 68HC000 that required less power. For the 128k, 512k, 512ke and Plus they either clipped on top of the CPU (e.g. a Killy Clip) or replaced the existing 68000 CPU.
Sources: BYTE, Computer World (CW), InfoWorld (IW), MacWeek (WK), MacWorld (MW), MacUser (MU), The Macintosh Buyers Guide (MG), MicroTimes (MT)
Note: Accelerators that support the 512Ke and Plus, can often be used with the 128K and 512K if the Apple 800K internal disk drive kit and it’s included 128K ROM upgrade has been installed.

Finding mixed info on this board’s memory expansion capabilities. The Apple Engineering Guide says that it does, but the table in MW 1990.02 page 129 says it does not.
Not sure if the SCSI port was optional, or included in all versions (high-speed SCSI)
“Pro-Board is a plug-in enhancement that combines acceleration, memory expansion, and high-performance large-screen display in one easily installed expansion card. The Pro-Board transforms a Macintosh 512K enhanced or Macintosh Plus computer into a workstation with the speed and power of a Macintosh II system, while retaining the portability of the original machine. The Pro-Board even includes a SCSI port. The Pro-Board SE offers the same performance enhancements for the Macintosh SE computer” (Apple Engineering Scientific Solutions Guide Winter 1989)

Note: Accelerators that support the 512Ke and Plus, can often be used with the 128K and 512K if the Apple 800K internal disk drive kit and it’s included 128K ROM upgrade has been installed. Also accelerators that include more than 4MB of RAM may need to use Connectix Virtual or Compact Virtual to access the additional RAM.

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.
It is Harris Performer2, Peformer2. Do you have more information on this piece of hardware, I can’t find anything on the internet ? Your description says “extended video” but was it in color? accelerated? did it used vram? Also, you mention it has a fpu, was it the 68881 ot 68882? was it memory mapped? Even an scanned review would be nice.
Thanks in advance
Hi Rick, I was able to find a review and an advertisement. The advertisement mentions the video out port. I have also sent a message to Michael Harris (the company founder) through linkedin to see if he has any documentation or disks from those days. Will post more as I find it.
It would be nice if documentation or drivers could be preserved for posterity. Thanks again.
Hi!
I still have a MacPlus with a Brainstorm I installed back in the day!
It boots, but needs a new analog card as the screen shimmies.
Hi, I’m trying to identify this LCII (and possibly other models) accelerator I have:
https://imgur.com/a/YvWANva
The only possible identifying mark I can find on it is the white sticker on the front that I think reads “STI50112”. When installed in an LCII, it appears that the CPU, FPU, and onboard RAM is recognized without needing to install any driver or extension. I don’t know if there is a driver or anything for it because I don’t know what it is. If I install 16MB of RAM on the accelerator, it’s all recognized and any RAM on the LCII’s logic board is ignored. Tattletech can’t read the CPU frequency (shows a really large number). Anyways, I’d really like to identify this accelerator!
Try posting on https://68kmla.org/, one thing I plan to do is redo this page with more photo to help people identify cards with no branding.
Hi – I added the Mobius 030 Accelerator Owner’s Manual to Macintosh Garden (a scan of my own manual from my 1993 purchase while in college).
