The port of ZCPR3 (v. 3.3) to CP/M 3 systems is in the late-alph-test
stage, and release is projected for January.  Availability will be
announced here.

Z3ON3, the workname for this version of ZCPR33, is implemented as a
CP/M 3 RSX; it requires no changes whatever to the bios or system
tracks, and can be rapidly loaded and unloaded.  I expect it will
run on most/all z80-based cp/m 3 systems, with no system configuration
required.

Most Z-tools run without change, and we are cataloging those requiring
attention.  Programs that use these functions will need upgrading:

	direct bios file i/o
	disk size calculation from the allocation vector
	references to zcpr3 internal addresses (show, h, ...)

(Conversion of zcpr3 to an RSX has been a major system-programming
task; I would advise against attempting it yourself without
a very complete understanding of the internals of the cp/m 3 bdos
and ccp).
