Whew! Thanks for restoring my sanity! Glad you got it working.
I don't know the IIsi RAM chip pinout, but there is probably a single line you can disconnect from the chip and then tie that pin high at the chip to disable it completely (like the RAS pin on a DRAM chip's data sheet I'm looking at). What is the IIsi RAM chip part number?
Will the SIMM RAM take the soldered in RAM's place, or is it set up to always appear above the first 1 MB of RAM?
