Very useful ... POWER by Pavel Breder

A swiss knife for CP/M (and also for early DOS computer) !

What Norton Commander represents for DOS, POWER represented it for CP/M. This program made it possible to manipulate files easily by number, can change memory content, can test and fix bad disks, can debug programs and have many other helpful functions - that was offered all in one program.

Major POWER commands:
DIR COPY REN ERA
TYPE TYPEH TYPEA TYPEX
RUN EXIT SIZE CHECK
STAT USER XUSER TEST
SETDIR SETSYS SETRO SETWR
RECLAIM DISK GROUP LOG
DS SPEED SAVE LOAD
READ WRITE READGR WRITEGR
DUMP DUMPX DUMPH DUMPA
MOVE FILL CM SEARCH
JP EX GO USR1
USR2 USR3 USR4 ?

A small company named "Computing!" (located in San Francisco) selled it for about $150, which was a lot just for a utility program.
But in 1983, not many programs had so many features.

Power was not only offered for CP/M-80, but also selled for CP/M-86 and for DOS... for DOS, it was a bit too late, also programs with a graphical gui had a much greater success (like Norton Commander).

D/L your appropriate version here:
CP/M-80 POWER Version 3.03 (Password utility included)
CP/M-80 POWER Version 3.07
CP/M-80 POWER Version 3.08
CP/M-86 POWER 86 Version 3.35
DOS POWER 86 Version 3.06

Any program/game here is only offered for educational purposes and for historical reason. It's barely done for fun, and pure non-commercial.
