In article <673@lzaz.ATT.COM> hcj@lzaz.ATT.COM (HC Johnson) posted
some Shareware documentation by Barry Orlando:
|  
|  This is a Shareware presentation of upgrading a 1040 or 512 to 2.5 meg.
|  It contains a description of the 256K and 1meg chips as well.  It should
|  also be simple to use this as a way to upgrade a 512 to 1 meg.

I have already seen this file in one of the online ST magazines.  Has
anybody tried this method of piggybacking the chips?  Did you succeed?
Also, can any of you hardware types comment on the design, etc.?

For those that have not yet uud'ed and dearc'ed it here's an
interesting tidbit:

|| All registered users will be sent a free utility disk which includes a
|| program to test the new RAM and instructions on how to further modify the
|| computer to a full 4 megabytes.

Either e-mail me or post followups.  I'll summarize if I get anything
interesting.  Thanks to all.
