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.

The first mention I found for memory upgrades were in June 1985 (for the 128K and 512K), and the first mention I found of an accelerator was Human Touch Computer Products Corp. Three to One Touch Board, adds a new 68000 CPU running at 12MHz and up to 3.5MB of RAM., the next was General Computer Company’s (GCC) HyperDrive 2000 in MacWorld March 1986, adds 1.5MB of RAM, a 20MB hard drive, a new 68000 CPU running at 12MHz, and a 68881 FPU, 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.

Accelerators

The following table lists the accelerators I have found listed in scans of Byte, ComputerWorld (CW), InfoWorld (IW), MacWorld (MW), MacUser (MU), or on the internet in general. In addition to the table, I have started recording information about each of the companies that produced the accelerators, specifically information about bankruptcies, sales, mergers and licensing agreements that led to the same accelerator being listed under multiple different names.
