You are wrong. Every MSX2 must have Memory Mapper. Even with only 64K of RAM,

I know Hydlide 3 and a collection of 100 games in 1 made in Korea (similar to

Hi to all,
I'm here again to talk about C.
In the documentation I have the author talks about MSX-C and he lists the

Hi all,
Ooohh, it's really hard to explain those Brazilians all about memory
mappers! (don't they have any?).
Some facts:
An MSX2 doesn't need to have a memory mapper to be a true MSX-2.
Example: Sony HB-G900. 64K RAM, no mapper, but true MSX-2, nothing
wrong with it.
Apparantly there ex

It is a FDC from National Semiconductiors.
They seem to have samples.
I have received 7 of these about a year ago.
(they shipped it to the netherlands at no costs for me)
They are PC FDC controllers, but that shouldn't be
a problem.
