I worked for Cray Research in the 1980s. A lot of the CAD software for the Cray 2 ran on a Z80 based CPM machine called the Intertec Suberbrain. Then we got a bunch of PCs from ATT called the ATT 6300 (Actually made by Olivetti). We figured out that if we replaced the 8086 in the ATT 6300 with a NEC V20, we could run all the Z80 software on the ATT 6300 by putting the V20 into Z80 compatibility mode. Saved a lot of work and time for us.

I used a Superbrain way back when and it was wonderful for its time.

Laptops didn't exist. Most other computers had separate boxes (screen, CPU, keyboard, floppies) that needed to be connected together. This thing was a practical, relatively nice looking all-in-one.

Then the IBM PC and its clones came, and the world changed.
