Testing RAM for a 4Mb A3000 Upgrade

OK, I'm not too much into DRAM. So would appreciate some assistance, please! I'm thinking of a Block of Memory 2 x 1Mx4bit attached to the 1MHz Bus (if it can handle that amount of data?). The test board would need the DRAM RAS and CAS generation plus any Paging requirements. There may be something ...

Re: ZOMBIES ATE OUR ROADIES!

If Stuart doesn't mind(?), duikkie, I'd like a more compact version for the MGC - Although the MGC can load more that one file, as long they are LOAD-ed, it would alleviate work elsewhere :D

However, there are sometimes links on the board to differentiate between 1M and 4M versions.
Wouldn't indicate there would be something to change?? Or are they 'passive' model identification?
