Subject: X on IBM RT w/EGA display.
Newsgroups: comp.sys.ibm.pc.rt

Imagine my delight at some guy wanting to trade HIS 6150-25 for my
'286 clone.  So now I have this machine and all seems to be coming
along nicely.  However, imagine my dismay when trying to bring up
IBM's rendition of XWindows on the EGA display that the machine came
with.  I get "No adaptor match found.".  I've installed all the
appropriate GSL stuff, created PTY's, and done just about everything
I can think of.  RTFM'ing shows that X wants to run on a 6153, 6154
or an 8058.  I can't afford any of these devices so that isn't a 
viable solution.

  My question: Does anyone know of or have any experience running
X on an RT with an EGA Display?

  Other questions: 

		This machine came with an IBM 5378 monitor, box
and AT-bus card.  Of course the RT won't recognize it.  Insiders at
IBM tell me it's meant to hook an AT up to a 370 and give it some
sort of graphics capability.  Does anyone have any experience with
this item.  I don't have/have never see/don't want to see a 370 but
would be delighted if this rather large and colour capable monitor
would run on the RT.  I know this is slim but hell... while I'm
here.

		 I have a VT220 hooked up to the 4-port asynch
which seems to work reasonably well.  Proper IBM Terminal cable
with a 25 foot 1:1 extension.  Now, the terminal works well 
until I happen to hit a key while the RT is displaying something
on it.  The port then hangs for any input to the RT, yet the
RT can generate output to the terminal just fine.  Pdisable/penabling
the port generates the appropriate login banner yet will not accept
keystrokes.  The only solution to the problem seems to be pdisabling,
unplugging the cable off the RT, penabling, and reinstalling the
cable in the port.  Or just rebooting the machine.  I've had this 
same terminal and cable hooked up to my old Xenix box and didn't
experience this problem at all.  However, I've worked with RT's
and used IBM3151 terminals and haven't run across this problem
either.  Does anyone know anything about this?  No, I haven't
attacked the cable with a breakout box yet.  I don't have one.


   Other relevant information:  6150-25, 2 R40 drives (give me more
diskspace.. Someone.. Quick), 4mb RAM, 4-Port Asynch, Floating
Point accelorator, IBM EGA Display-card, Tatung EGA monitor, 
AIX V2.2.1...
