[comp.sys.mac.hardware] RAM upgrade on Hypercharger20?

kenton@space.mit.edu (Kenton C. Phillips) (11/16/90)

I have a friend who owns a Mac SE with a GCC HyperCharger20 accelerator
board.  He wants to add RAM to the accelerator board, but has no
documentation on it, so he doesn't know how to set the jumpers.
Playing around with the jumpers has not illuminated the problem.

The SE main board has 1 MB RAM.  The Hypercharger also has 1 MB.  He wants
to replace the four 256K SIMMs on the Hypercharger with four 1M SIMMs.

Does anyone know what the jumper settings are for this?

Please respond by e-mail (kenton@space.mit.edu), as I don't normally read
this newsgroup.

Thanks in advance.
