Hello Apple geniuses
I had some plans with my dusty Apple //e (which still worked last year, albeit some r/w errors with floppies) but decided to do some reading first.
Reading the IIe owners manual I discovered the self diagnose function: solid Apple key - CONTROL - RESET
I did that and got:
RAM: F13 F12 F11 F10 F9 F8 F7 F6
The other self diagnose method (power on holding solid Apple key) only gave me
RAM:
and nothing else
I read this article http://support.apple.com/kb/TA38047 and concluded all my RAMs might be failing 
However, after removing my DISK II interface card, whatever I do to enter self diagnose ends up showing just
RAM:
I could really use some advice. I just want my Apple to work like it used to. I'm not afraid of the soldering iron.
Thanks in advance!
i removed the 80COL card but it didn't change anything
still freeze after
RAM:
RAM is cheap. Just buy new chips. They can be had for about $1 each.

The IIe takes 64k x 1 bit DRAM in a 16 pin DIP.
Thanks Dog Cow,
Will do that.
anything specific i should watch for?
the site says:
"4164B-12S 64K x 1 bit 120ns DRAM. 16 pin DIP. "
any gotcha's concerning slower/higher speeds or anything?
is the PCB and its chips very ESD sensitive?
Not likely. 120 ns is faster than the Apple II requires, but it will still work, of course.
Hard to tell. I've never had problems with static, but it's always best to take the usual anti-static precautions.
i've the same problem,how did you resolved?
