[comp.os.cpm] CP/M 3.0 CCP replacement

ACB.COR@OFFICE-1.ARPA (Alan Bomberger) (09/23/87)

Has anyone attempted to write a custom CCP for CP/M 3.0?  The idea of writing 
such a beast in some language other than ASM is tempting.  However, the thought
of dissecting the LOADER from the existing CCP and learning how to get it as 
part of the new CCP and loaded into memory as an RSX is a bit daunting.  Has 
anyone done anything along this line?  I know it is a  bit late for CP/M 3.0 
but I have run out of things to do on CP/M 2.0 and am resisting buying one of 
these new machines where you can't fiddle with the BIOS (in ROM).  What is a 
home computer for if you cn't program it?  So I am converting to CP/M 3.0 
instead.  I would try Turbodos but the supplier is very closed lipped about 
source and my copy for the NorthStar has no BIOS source.  Starting from scratch
there is a bit daunting as well.  Peace

Yes, Alan, there's at least one:

CCP105 is a good implementation of ZCPR2.  It's on simtel20.arpa.

I'm actively working on a ZCPR33 port; it's too early to project a
date.

There is a CCP replacement for CP/M-Plus available from SIMTEL20...

Filename			Type	 Bytes	 CRC

Directory PD:<CPM.CPM3>
CCP105P.ARK.1			BINARY	126592  3993H

The filename is really CCP105+.ARK but the + was  changed to "P" for
the Tops-20 directory here.

This file is also available from my RCP/M and from GEnie's CP/M
RoundTable.
