What a coincidence, but I just read a magazine article which discussed
this subject. I am *also* not a hardware buff so I also would appreciate
comments on the subject, in general, and on my article, in particular.
The article appeared in the French microcomputer magazine "Micro
Systemes", July-August 1988 issue. The article described the theory of
accessing more memory on a 1040 ST and then showed a printed-circuit
diagram of a circuit that they called "Super Glue" which would override
the "Glue" chip in the 11.5 Megs available over the 4 meg limit. In fact,
the circuit adapts the ST to an external G96 bus on which, I suppose, the
memory should be connected; there is *no* memory on the card, just a
couple of buffers and 3 PALs. They mentioned that certain parts of the
installation were quite delicate. In fact, when everything was assembled
they seemed to imply that the result would probably not fit back into the
ST case; they suggested buying another case.
I would appreciate any knowledgeable information on this subject. Has
anyone read this article? (I don't know how hard it is to get in the
U.S.) As always, I still (sigh!) don't get the newsgroups, just
info-atari16, so please reply directly to me. Thanx.
You do not have to reply before going on vacation -- so have fun first.
