Ah, but how many of you have the same thing for the PCjr?  Or am I the only 
one?  I have the tech reference as well as the hardware troubleshooting ref 
(along with all the hardware loopback dongles for the PCjr).

Or is PCjr stuff not collectable in any way?  It's more rare than 5150/5160 
stuff, to be sure...  I feel like I'm the only one with PCjr stuff :-)

Along these lines, is there any electronic copy availble of the PC tech ref.? 
I ask because I am doing some CGA programming and would like to verify the 
information I have against the official IBM docs.  My PCjr tech ref also goes 
over the Motorola 6845 registers, but it is decidedly PCjr bent (for example, 
it immediately talkes about how all of the first 128K can be used as display 
memory, something obviously not true for a real 5150/5160).
