If you think that's strange you should have seen the Tektronix 8051 This construction reminded me of
1970 style 'inteligent' terminals where screen buffer was more like a
code of some sort to be executed by the diplay processor which was a
micro code engine itself.
And that reminds me of the Tektronix ASCII Terminal I
rescued lately.
Characters are drawn only once and the analog "memory" display tube
keeps the dots fluoresceing. No screen refresh! This is one of the
Terminals where you can see that Tektronix is well known for
oscilloscopes... computer. It also used a storage tube for a CRT! You
had to
periodicly press an Erase button to clear the screen!!
