I do ask for one thing, if it's not too much trouble; Create a dipswitch arrangement where the user can select from 1, 2, 4, 8 or 16Mb out of the 16Mb cartridge 'REU'. The reason is that some people, like yours truly, would put such a REU into a RAMLink. If a 16Mb REU were put into the RAMLink on the RAM port, the RAMLink's onboard expansion ram would be pushed out in favor of the RAM on the REU. So, a user could manually configure this REU to be lower, say, at 4Mb or 8Mb and still be able to plug it into the RAMLink and still have access to the RAMLink's onboard expansion ram.
