While PuTTY is functionally "OK" on both Linux and Windows, it is not 
particularly "accurate" as an emulator of the real VT102 (which it 
identifies as)

A ROM based emulator may be more accurate, in addition to having more 
lifelike fonts etc. I have no personal experience with Mame.

So, in all, it depends what you are looking for. I feel most comfortable 
using PuTYY with the "Glass TTY" VT font (look it up, nice piece of work!)
