I have read about a video upgrade for the C128 which would give it 64k of video RAM. What does this do for the machine?

It upgrades your video information from its present 16k
to 64k, which in turn allows you to view on your monitor
Hi-Res graphics, and color information, that would not
otherwise be available.
I am making available to anyone who wants it everything
necessary for the upgrade for $13, including postage. This
would include two #4464's, properly rated, and made by Hitachi,
two matching IC sockets, and detailed installation instructions.
You should be familiar with soldering around PC boards to do this
yourself, else have a pro do it for you. For the set, send your
check to: Howie Herman, 229 East 28th Street, New York, NY 10016.
Shipping will be by UPS, so please no PO Box for addresses. Thanks.

Software to do the latter was published in the Transactor Vol-7, Issue-1 (July 1986). -- David Paulsen - CHARTER MEMBER, WILLIAM WINDOM FAN CLUB ..uunet!nuchat!seven "It had a maw that could swallow a DOZEN starships!" --Commodore Matt Decker, chewing on the scenery again
