[comp.sys.amiga.tech] a500 ram failure

Hi there,

Using the recently posted program MD, I discovered that I have a flaky 
ram chip in my amiga 500. When I use malloc(1024) often enough to get a
pointer to 0x254ef, I find I can write 0x080 to it, but always get a
return of 0x00. I think I have to replace one of the 256x1 drams.
Can anyone give me a hint on which chip I have to replace and maybe some
directions on how to replace the chip. I am not totally inexperienced in
soldering, but then again I could use some technical advice. Would it be
advisable to insert a socket or is just piggybacking with disconection
of the data pins a good solution. 
Any help will be appreciated.

			Thanks, Wim Letzer.
