CP/M on a TRS-80 4P

I bought the hardware…I bought the software. Reading this. And wanting to run CP/M…found these images.

Using the trs80gp emulator in 4P mode…
Using cp22232a.zip from Montezuma Micro, as a guess.
pointed to MMCPM232.DSK and replaced diskette drive0
Pressed the Reset button from the File menu
and…

Success!

Running 8-bit software on an emulated 8-bit Z80 hardware. Looking at the above directory it seems to me that Gary Kildall…the creator of CP/M (which was created in 1974) must have been influenced by DECs OSs. I see PIP which I am familiar with as a RSTS/E utility…and RSTS came out in 1970. PIP stands for Peripheral Interchange Program, and it seems highly unlikely that someone would come up with a utility called that unless influenced by DECs OSs. MOVE…yes! COPY…yes! DELETE…yes! RENAME…yes! PIP…NO! A Wikipedia article says DEC created PIP in the 1960s.

Gary was a very interesting person and was also co-host with Stewart Cheifet of The Computer Chronicles, a old PBS computer show. CP/M was almost chosen as the OS for the IBM PC.
