memory corrupt/schematic sought - AE RamKeeper

[djc@koko.csustan.edu (Dennis Cardoza)]

Hello -

I am having memory corruption errors with my GS.  I have a ROM 01 with
an AE RamKeeper and a Sequential Systems 4 Meg card.  I usually have an
800K ROM disk and an 800K RAM disk set up.

If I have both cards installed and let the cards draw power from the GS itself
(by disconnecting both the battery and plug-in power supply), everything
works fine.  Things seem to work OK when the battery powers the system.
As soon as the power supply is plugged in, things mess up.  The ROM
disk checksum will fail, and sometimes the RamKeeper CDA fails with
jumbled text.  I have put an oscilloscope on the power input, and the
incoming ripple is extremely low.  Has anyone seen this before?

More importantly....

	Does anyone have a schematic for the AE RamKeeper?

I might be able to troubleshoot the circuit if I had one.

	Thanks in advance for your help,
