How easy is it to damage an IBM CGA display?

[Michael B. Brutman]

All is well - the industrial CGA display is happy being connected to a 
real CGA card.  It's quite the looker too.  People at the office are 
impressed, possibly not in a good way. ;-0

The machine (a 5160) has the monochrome adapter (Hercules), a genuine 
CGA card, a 3Com 3C503, memory, serial, floppy and a hard disk 
controller.  It has 512KB of RAM and a full height 10MB hard disk.

NCSA Telnet *was* running on before I put the CGA card in.  (I had a 
Cirrus Logic VGA card in it yesterday.)  Now NCSA Telnet is hanging on 
startup after reading it's config file.  I'm having a hard time 
believing that the CGA card replacing the VGA card broke it, so I'm 
going to have to undo my changes and try again.  My own TCP/IP still 
works, so I know it's not a hardware conflict.  (It's pretty hard to get 
CGA to conflict with anything.)
