[comp.sys.amiga] A2000B + A2058 + A2000A MemCard???

niesemc@econ.vu.nl (Marco Niese) (09/14/89)

If I have an 1MB Agnus installed, I lose my $C00000 memory. I like to run
all kinds of demos/mega-demos and I'm afraid -because of ill programming-
that they won't run.

If have a A2058 installed, can I also install a Memory Card which was designed
for the A2000A to give it 1MB/1.5MB of RAM? Will I get back the $C00000 RAM?
Will I have 9.5MB/10MB available or is the card not AutoConfig-ed or non-
installable?

A less elegant option could be a switch connected to J500 (will void
warranty? May destroy Agnus if switched too soon after power-down?)

Maybe someone knows the answer to this problem... Thanks.

It's really difficult to count on having $C00000 memory; basically, you'd
have to intentionally do something stupid.  In fact, only a very few programs
depend on any FAST memory being in the system at all, and that's usually a
bug in the program anyway.  I wouldn't worry about it.

Are you talking about the 512K/1 Meg CPU slot card for the original A2000?
That only works in the original A2000, not in the "B"2000.

No, don't do that.

It's not a problem.  Really.  Nothing is going to count on $C00000 memory
being there, and I sincerely doubt that you're going to run into many things
that require more than 9 megs of memory.

True.  In fact we've known for a long time that you don't really
need more than 640K. :-)  :-)  :-)

(Sorry, couldn't help myself.)

Remember when 64K seemed like a massive memory?

Just wait till Amigas to come stock with 100 MEGs.
There'll be applications that can eat it all in one bite ;^).
And we'll all wonder how we ever survived on a mere 9 MEGs.
