• Requires > 1 Block?

CCP/M-3.1 barks at int 10h

sort out why cpmtools refuses to work with 320kb (for testing I use single face 160K images). ibmpc-514ds does not seem to work.
depending on libdsk usage, format support changes too

• 320k
• 160k
• 720/1440k
  and
• CP/M-86 vs CP/M-86+

Study, recompilation/rewrite and patch of Date, Show and Dir and in the meantime regress test. of backward combat of Y2k tools from concurrent dos?

transparently support vt100/vt52/bios in conio
mode/atinit/pceinit/cls are impacted

deliver a guide to rebuild CP/M-86 from its sources with all the patches, AT support and 2020 look and feel. It works well but publishing the fixes and the code may not be allowed. all sources of information and code to start were found on (http://www.cpm.z80.de/source.html). It just required a lot of effort to compare/consolidate code, annotations, patches and comparison with existing binary versions. A lot of fun.
scripting of patching from official repository

Use dos function 32h to use int13h function 8 on dosplus
dosplus displays wrong hard disk number on INT 13h Function 08. using BDOS 32h, we can retrieve the real int 13h. that would allow correct calculation....

Add attrib tool and API: function 30
Support for sys/dir

dosplus weird cusor behaviour after using graphics. the secret lies in understanding what happens behind mode.com CO80.

Explore further CP/M-86 Big Brothers (PCP/M 2.04 and CCP/M 3.1). At first glance, they
are giving you better CP/M-Plus like experience than the rough CP/M 2.2 interface of CP/M-86 but CCP/M-86 has a lot of quirks and PCP/M Keyboard configuration is a bit tricky (Fully IBM PC compatible?) .... to be explored

• support ccp/m anddosplus in mode.cmd and gfx (status line, cursor ...)
• BDOS 3.1 to 4.1

cp equivalent for cp/m-86

try to pull/port a version of Emacs or VI on CP/M-86. I could not find one working out of the box (I am working on figuring out an elvis (https://github.com/udo-munk/stevie) and femacs in assembler ....
