SGI Indigo keyboard / mouse / converter wanted

[Douglas Taylor]

Jules,

I don't have a solution, only the same problem, but with a Tektronix 
4200 series graphics terminal. Keyboards are rare, there is one on ebay 
for $700, yikes!
However, I do have 2 of these terminals and one working keyboard.  Was 
starting to go down the path of intercepting the startup, POST exchange 
that occurs, then trying to adapt a common PS/2 keyboard.
I was looking for minimal capability, not perfect emulation.
