I am somewhat curious about the ADAM Computer core that is being developed. I hope whoever is doing it is knowledgeable about the machine and it won't just be based off something like the ADAMem emulator which is available (and has its shortcomings). Since the Phoenix will allow you to hookup a keyboard, it can basically become a replacement for the ADAM, but there are several things I would consider important to include.
1.) It needs to support two disk and two data drives and have the ability for you to "swap" disks (or data pack) images. If you run an application, you don't really want to save your work back to that disk or ddp, so the ability to swap our that disk or ddp for a "blank" one is important.
2. Steve Pitman's "Virtual ADAM", the front end for ADAMem, allows you to actually "print" documents, although this feature might be unknown to some people. If you use SmartWriter or another application to print your work in Virtual ADAM, the document is actually printed to a text file. Clicking on the picture of the printer that is displayed within the emulator brings up a directory of the files you have printed. This would be another nice feature for the Phoenix ADAM core.
