The PC-XT/370 contains a card with a 370 processor on it.  This includes
a couple of Motorola 68000s with a custom microprogram to handle 370
instructions and floating point.

This gadget is intended as an alternative to a 3270 terminal at an IBM shop. 
It really isn't a stand-alone machine, it needs to be wired into a 3274
communications controller and talk to a mainframe running VM/CMS.  (Don't you
love all these funny box numbers?:-).

The operating system is pretty much regular VM/CMS.  A large part of the
PC's hard disk is used for the user's local files (the A-disk in VMspeak).
The PC user can link to other minidisks on the mainframe to access system
files, etc., just like one links to system minidisks when logged on to a
regular VM/CMS system.
