If you are asking if it is configurable to select from

1024k chip / 512k fast

I dont think so, not yet.


How does the 2mb of RAM on the board get allocated into fast and chip at the moment?

It is hard coded in the MiniMig verilog source.

Looking at the source code MiniMig1.v and Gary.v MiniMig has 1Mbyte of Chip and 512Kbyte of SlowFast RAM.

I do not think this was a valid configuration in a REAL A500 without a Fatter Agnus, but probably the Fatter Agnus had other features not yet implemented in MiniMig.


So does that make the Wikipedia page incorrect!?  :-o  Who'd have thunk it!

It's not "allocated". The HDL code simple define memory ranges and interpretate certain areas of the memory as a specific type of memory.


Have you not just described memory being 'allocated'?

Are these getting added to the wiki page mentioned in this thread?

In the 'Works' column it says FAIL for those that don't work.
