Opening Mc Naught and Co. on the 1st March 1984, my first computer was an Osborne 1 with cpm operating system and dual 32k floppy drives. I managed to start the legal firm using the accompanying basic accounting software and WordStar word processor to run my legal accounts and handle all letters and contracts.
I ended up with a collection of several dozen floppy disks the data could be stored on and I could connect my daisy-wheel typewriter at reception to the computer and print out my documents there.
At the end of each day I could pack up the clip-on keyboard and carry my computer home to continue working.
