        Well, I haven't the foggiest what the enduser upgrade will be.  Or if
there will be one.  Requires a lot of mods to a 2.2 BIOS to take advantage of
some of the performance enhancments.

        CP/M3 is capable of doing disk I/O 10-20 times faster than optimized
2.2 systems, especially on hard disk systems.  It can run with the BDOS mostly
banked, and use alternate banks as L.R.U. directory caching and deblocking
buffers.  The deblocking is done by the BDOS, not the BIOS.  There is a whole
new set of utilities, it will come with RMAC, LINK, LIB, a MP/M-like SET and
SHOW instead of STAT, rename with wildcards, console I/O redirection to/from
disk, lots of other goodies like that.  Most users should wait for their system
suppliers to offer preconfigured systems, unless they have implemented their
own 2.2 BIOS's.  We are finding it increasingly hard to give tech-support to
individuals trying to write BIOS's.

        I guess I could go on for a while, but I mainly know about the
internals of the BDOS-BIOS interface, and not much about the enduser interface
level of the system.  Ask specific questions, I'll try and answer them.
