Hello,
on my 4000/60 when I issue the command

sh mem

I Got these results

MEM_TOP=02000000
MEM_BOT=00000000

 MEM_NOT_AVAIL
---------------
01FBE800:01FFFFFF

that is if I make the difference between the two memory values = 417FF
that is about 200KB

this means that 200KB of RAM on 32M total I have are not avaliable ??
coult it be because of 1 pin of a SIMM module socket is damaged ??
This could be the reason of the MEM_NOT_AVAIL message ?
and if these 200KB are not avaliable all the rest of MEMORY will be
addressed correctly even if that PIN is damaged ??

thank you

Rick
