A ROM emulator for the 71B

Mark, this is VERY cool!

As a fan of the TITAN I would ask to be put on your list when/if you decide to keep one. I am so ready getting to play with your final product once you are ready to take orders.

Do you plan to support more than one ROM image mapped at the same time ?

A quick update on development progress, and another picture to answer your question. I took some time to reexamine the means of determining how a Saturn address is mapped to a ROM image in flash. I can now enumerate all ROMs and support a hard configured ROM like that for Forth. Have a look at that VER$ output line!



I have the board programmed with Forth (16K), Math2b (32K), JPC rev E (32K), and the Forth-hrd ROM (32K). There are no longer any placement restrictions as before. It's really nice to have all the features and BASIC extensions in J-F's two ROMs. Forth will be interesting to play with as well. Anyone care to describe their favorite use for this development ROM?

Happy Thanksgiving!
