You may remember that I too built a CP/M machine which I called the 
Xerloot, also with a floppy drive (which could read both sides of a 5 
1/4 diskette, if you punched the diskette at the right place  :-)
I still have it, I think, somewhere in our basement.

What I liked about CP/M was that if you wrote some code and made an 
error, the Editor would come back   --sometimes--   with the comment 
"/what ?/"
