I have been working on a project the last few weeks and came up with this:
While I have only tested it with a few titles, it appears to run most .z3 Infocom data files without alteration.
It requires a CFFA1 card as mass-storage for the interpreter and data file due to the paging that the interpreter uses, and the extra RAM required. I've tested it with OpenEmulator and it should run on Replica-1 systems as well.
Hopefully, I will have a chance to run it on the Apple 1 that shows up at Vintage Computer Fair Midwest in late September.
