    It is not new since we have discussed in the newsgroups couple years
    ago.

    The Rocketchip was another accelerator on
    a chip that went head to head for a while with
    the ZipChip. Instead of 4 and 8 mhz, they
    offered 5 and 9 mhz. However, it turned out that
    the people who were developing the Rocketchip
    once worked for Zip Technologies, and Zip sued
    them and won for patent infringement, so the
    Rocketchip was removed from the market. Zip was
    the only one who had one of these types of
    accelerators out then. Both Zip and Applied
    Engineering had a GS Accelerator on a card-
    -you can find both still around.
    Interestingly, Zip originally announcedd a GS
    accelerator that was supposed to be another
    accelerator-in-a-chip, but it turned out to be
    too complicated to do so they went with the card
    format.

    Interesting side point: At one time Applied
    Engineering started to develop an accelerator
    card that incorporated a rocketchip on the card.
    They were just about to release it (or did with
    very few units sold) when they had to stop selling
    it when the above lawsuit was settled. They had
    started to advertise it in all the A2 magazines,
    too.

    The AE TransWarp II uses the RocketChip Technology to run about 8MHz or so. I love it! Turn off the TransWarp startup graphics and watch folks jaws drop as the //e zooms through programs with screen refreshes that put modern laptops to shame.

    Does the Rocketchip work with the IIgs?

    No: it's a plug-in replacement for the 6502, and the IIgs uses
    a 65816.

    But let's not forget that "RocketChip technology" is really Zipchip technology, which was pioneered as McT SpeedDemon technology.

    The founders of Zip Technologies Inc. were the people who designed the SpeedDemon card, who had the further idea of reducing it all to a multi-
    chip carrier that plugged into the processor socket.

    RocketChip was formed by former Zip employees who left to duplicate
    the Zip work under another name.

    When Apple decided to license a cache-based acceleration technology
    for the IIc+, the only real contender was Zip, since they had clear title
    to the technology--as its creator, not as a licensee.
