Nah, working for a company providing inventory control and order entry systems for auto parts stores. First computer-related job I had. In many ways, those multiuser CPM machines were vastly superior to anything the IBM PC and DOS worlds came out with for years hence - to add a user, all you had to do was drop in a new slave board and hook up another terminal.
I ran an entire company on an S100 bus CPM machine for several years.
We used WordStar and I wrote the acocunting software myself -- using some Z80 assembler functions.
I had to develop my own memory management modules to devise my own simulated virtual memory.
Ahh, the gold old days. When real programmers managed memory directly.
