[comp.sys.atari.st.tech] How to add 512K to a 520ST?

kees@duttnph.tudelft.nl (Kees v. Walraven) (05/30/91)

Hello, 

	I am a proud owner of an old 520ST with only
512KB of memory in it. Can someone tell me how to add
512KB of memory more with 16 41256 chips ?

	Thanks,

Kees van Walraven

There is a file named "1megupgr.arc" containing all infos requested.
I found it on sol.cs.ruu.nl (131.211.80.5), directory ATARI-ST/doc .
