Is there an on-line source for installation instructions for the Levco
Monster Mac 512K upgrade? I Googled but couldn't find much info at all.

I just got a 512K that has one installed but it's possibly defective or
not installed correctly.

The 512K boots from a System 1.1 floppy but there is a loud buzz instead
of a boot beep and there is no happy (or monster) Mac, just a blank
screen until the system starts to boot. I can't get a system sound but
Pina's test disk produces normal tones. 

AFAIK, the Monster Mac board should raise the total memory to 2 MB but
"What? 1.0d17" reports the memory to be 512K and the Mac to be a Plus.
There doesn't seem to be enough memory to boot from a Sys 4.x disk.

Should the original ROMs be left on the MoBo? They are.

Thanks for any assistance in getting this upgrade working, Hardy
