sean: I think the MN14xx can be dumped electronically, I saw something about it in the data sheet I think, it's been awhile. I remember looking into it when you did the computer perfection.

I can dump the D650C with the D55x rig I already have. I dumped one I found cheap on ebay to test.

I don't know much about the toshiba part- there's an LCD driving toshiba MCU in that vtech learning window as well (and SP0256 speech chips and ROMs that I have dumped).
