What is a $2 Tech manual / $2TM?

Chrysler used to produce a technical manual for the DSMs, that dealt less with nuts and bolts and more with the theory of operation of virtually every major component on the auto.  Unlike the shop manuals, it tells you not what, but why. This manual used to sell for a mere $2.00, and is now referred to as the $2 Tech Manual.

Unfortunately for the DSM community, the $2 manual was only offered for the 1990 model year and was subsequently dropped from production.  All is currently lost, though, as Vineet Singh's DSM Backup Manual CD-ROM is offline. It included the $2TM and tons of other great info.

I have never seen the Vineet CD-Rom, all this content may be what was on it.
