My PC Techref is the first generation edition.  Because my father, as an
IBM employee, bought one of the first PC's on the market and bought
'everything' with it.  So my Techref has the distinction of only
covering the 16-64K motherboard.  (And, damnit, I don't have
'everything' that he got, just that manual.  By rights I should have his
'black paint on power supply' 'black painted card brackets' PC1 system,
which I at one point upgraded for him from 180K to 360K floppy disks. 
BUT I DON'T!!)

My 'XT' Techref isn't really that.  I have the IBM Industrial Computer
Technical Reference Manual set, which is a superset of the XT. 
Apparently the Industrial PC was an XT motherboard in a ruggedized
industrial case, and all the options and add-ins were available, so are
included in the Industrial techref.  I also have a two volume 'Options
and add-ins' Techref set, which is two slipcovered books with just the
options and what-not stuff.  I think it dates from the pre-XT era.
