Technically the 8088 processor was released in '79 while the 5120 was 
released in Feb '80.  The System/23 with the 8085 was released in July 
'81. The 5150 PC was released in August 1981 more than a year after the 
5120. The 5100 itself was released in '75, and the 5110 in '78. Same PALM 
processor throughout. The 5110 had more I/O like floppy interfaces, while 
the 5120 had a larger screen and 2 built in 8" floppies. 

The company I worked for bought the 5120 and I created an inventory 
control system on it but my personal machine at the time was an Osborne 1 
CP/M 'portable' that I bought in April '81. I don't remember when I got 
around to buying a PC clone, maybe '84? It was one of the brand x mystery 
boxes with the turbo switch.
