Talk:CP/M
From Academic Kids
Hmmm, the name for the copy command on the old PDP-11 (or possibly PDP-8, I'm not sure which) was "pip", n'est-ce pas? What is the connection there?
Do you know what OS on the PDP? I think PIP in CP/M stands for Peripheral Interchange Program, but I am not sure, will look up at some point (I think I set a set of Digital Research CP/M docs somewhere). --drj
There were several OSs on the PDP. I myself used RSTS/E on a PDP-11/70, and it used PIP. --Alan Millar (nice reference --drj)
The "pip" command (indeed standing for "Peripheral Interchange Program") was the swiss army knife of CP/M -- it could do copys, moves, and several other file operations. It was designed to know all about the various peripherals (hence the name) and how to copy, etc. to each of them. -- NickelKnowledge
Why not simply CP/M? We don't have to my knowledge any convension that says put operating system to all of articles of operating system. -- Taku 23:43 Apr 4, 2003 (UTC)
PRESERVED HISTORY OF CP/M (pre-merge and rename):

CP/M stands for Control Program Monitor and was an
early operating system for Intel 8080 and Zilog Z80 based computers.
It was normally distributed in its raw form on 8 inch floppy disks.
CP/M could be implemented on most new 8080 and z80 based systems by writing an interface layer, called the BIOS, for your particular computer then using the largely generic rest of the operating system largely unchanged. It was thus fairly portable amongst different machines with the same CPU; this made it popular, and much more software was written for CP/M than for operating systems that only ran on one brand of hardware.
Hundreds of different brands of machines ran CP/M.
WordStar, one of the first widely used word processors, was written for CP/M.
Later a version of CP/M for the Intel 8086 (CP/M-86) was written; it was an alternative to DOS for IBM PC's. DOS proved to be much more popular.
In many ways CP/M was a predecessor of DOS, many internal mechanisms of early versions of DOS were clearly inspired by those of CP/M.
The user interface of DOS however was a bit more friendly. Compare for example CP/M's copy command.
PIP <destination filename> <source filename>
to DOS's more intuitive
COPY <source filename> <destination filename>
