I lost my ROM, but there are copies on the internet. (I pulled all of the chips when I was in middle/high school, intending to build a computer of my own design, but never completed the project, dunno where they ended up.)
I also had a book with very thorough documentation on the hardware, but I don't know where it is. Dunno if my parents still have the tapes. It had the tape format documented.
It looks like "MESS" supports the interact, dunno how well though. After writing that post I looked it up, got it to run "Add-Em-Up", and let my toddler play with it. It appears to have a french keyboard mapping, however, so I'm guessing it's a modified Hector emulator.
Sorry, when I said "I was unable to save it all" I meant the entire computer. I do have a complete ROM and was able to successfully extract it.
I've got some documents including schematics and some of Interaction and Micro Video magazines. I was able to determine the bytewise format of the tape data (such as the dumps on archive.org) from reading the disassembled ROM, It's pretty simple as you can imagine. There is very little circuitry driving the tape drive so I'm confident that it's just toggling between + and - tape bias and the timing determines if it's a 0 or 1 bit. I looked at the wave form of a cassette rip in an audio editor and it looked pretty clear. I'm sure with a little work I could extract the data although there are probably tools that would help clean up the audio.
I had no idea MESS had any Interact support (they certainly seem to do a good job making their web documentation has hard to use as possible) I'll have to give it a shot at some point.
