[Oberon] Re: Oberon on ULX3S explanation

Wojciech,

According to Wikipedia, chips up to 2 MB are available for 
asynchronous and synchronous uses.

Therefore a board with 4 or 8 MB should be quite feasible.

This and other messages suggest, to me as naive reader, that you are 
reluctant to commit to SRAM on your RiskFive; still considering SDRAM.
Therefore I wonder whether cost is a concern.  But RiskFive is a 
high-end board.  Therefore unless the cost is extreme, it should be 
tolerable for RiskFive.
