Hummingbird Exceed, which is a terminal emulator I need to access my Alphaserver running OpenVMS. OSX terminal connects fine, and emulates a VT-series terminal OK, but I can't find a way to make OSX/terminal recognize a DEC keyboard. As anybody who's ever used a VMS editor knows, working on a keyboard without the editing keypad is only for emergencies. So when I got rid of my last PC, I had to install XP on a MBP or drag an old VT520 out of the barn.
Also I have some specialized RFID software that's only available for Windows. Since I shut down my company I only have to use it two or three times a year, and doing so on the MBP/XP should work just fine.
I will say that just as soon as I connected the MBP/XP to my network, it found my NAS and held onto it perfectly, over reboots. My main OSX (Leopard) complaint is that working with my NAS box is always a big headache. Finder finds it but won't open it, or doesn't find it...it's annoying.
