emulatorII-list

Just got an EII yesterday. 
1st few times switched on, it got to boot screen, and no further.
So I opened up, reseated a few memory ICs around what I think is first segment (IC13 area?) - used some deoxit and replaced.

Then this time, it booted up and all seemed good. A Bank loaded. I then tried to load a bank from another floppy, started loading, then after a bit froze and blanks screen.

Since then I have removed and reseated just about every IC on the digital board.

Generally all I get is black blocks on the top row of the LCD, nothing on second. And usually ALL of the LEDs lit.
about 1/10 times I might get the boot screen, but no further (doesnt try to read discs).

So in theory most of the machine is OK since I got as far as loading 1 bank.

Wondering if this is a bad connection somewhere.

Maybe RAM/Scanner problem?

Can any suggest anything I can try?
Which Ram ICs should I check first,
Any tips appreciated.
I am very good with electronics, however, not too familiar with EIIs (but learning fast!)



BTW, oddly, my boot up screen is unique(?)

custom? maybe just the message has been changed? (maybe Mulhouse is one of the previous owners?)
