*
* Motorola MVME-350 6U Intelligent Tape Controller driver, initially derived
* from hk68v10.c
*
* 31/08/2015
*
* I baught this board from http://www.retrotechnology.com without documentation.
* It has a Motorola 68010 CPU @ 10MHz, 128 Mb RAM and two 2764 EPROMS with
* QIC-02 tape controller firmware. The board also populates a 68230 PIT and loads
* of descrete TTL components.

* History of Motorola VME division (https://en.wikipedia.org/wiki/VMEbus)
*---------------------------------
* When Motorola released the 68000 processor 1979 the ambition of the deisgners
* was also to standardize a versatile CPU bus to be able to build computer
* systems without constructing PCB:s from scratch. This become VersaBus but the
* boards was really too big and the computer world already saw the systems shrink
* in size. Motorola's design center in Munich proposed to use the smaller and
* already used Euroboard form factor and call it Versabus-E. This later became
* VME which was standardized in the VITA organization 1981
*
* Misc links about Motorola VME division and this board:
* http://bitsavers.trailing-edge.com/pdf/motorola/_dataBooks/1987_Microcomputer_Systems_and_Components.pdf
*

* - Setup a working address map (STARTED)
* - Get documentation for VME interface
* - Add VME bus driver
* - Hook up a CPU board that supports boot from tape (ie MVME-162, MVME 147)
* - Get a tape file with a bootable data on it.
