From what I can see, the "decoded" enable line to the ROM sockets (depending on which issue board and what chips, mask ROMs or EPROMs were fitted) is mapped to both the OS ROM space and the 16k for the ROM cart. port.RWAP wrote:Just wondering what these Minerva + TK2 upgrades will be - remember the ordinary Minerva uses up the QL's standard 48K ROM space, and does not include Toolkit II normally....Dave wrote:There will also be a plentiful supply of Minerva upgrades which also contain TK2.
So getting a 64k byte EPROM to work in one of the sockets is not that hard, it would be mapped to the OS ROM space and to the ROM cart. space.
But a question for Dave: Do the EPROMs for your existing Minerva boards (that you are selling on your site) include Toolkit II? Or are you talking about a new version?
