[net.micro.mac] >512K for Hypermacs: followup

s255@sol1.UUCP (alcmist) (12/13/85)

    Several companies which offer RAM upgrades past 512K claim that their
upgrades are compatible with the Hyperdrive.  Among these are Beck Tech
(800-227-2400), Micro Conversions (800-237-8622), and Mass Tech (800-
447-1215; they're planning to make a Hyperdrive-compatible upgrade 
available in January).  I'm sure there are others.
    A while back I asked whether anyone on the net had actually used
a Hyperdrive with a >512K upgrade.  Here's what I found:
    I did not hear from anyone who has a Hyperdrive and >512K in the same
Mac.  The only informative reply I got was from an employee at GCC (the
manufacturer of the Hyperdrive).  He said that GCC does not certify any
third-party upgrade as Hyperdrive compatible and that installing one would
void the Hyperdrive warranty.  Speaking strictly for himself (i.e., this
is not something GCC says) he commented that rearranging Hyperdrive 
components to accommodate extra RAM could easily cause trouble.
    If anyone of you have seen an obese Hypermac, please feel free to 
post comments.
