I watched a youtube video about the the Apple II. computer. For those who doesn't know about it, Apple II has a MOS 6502 CPU, and the system was introduced in 1977 and was used in american schools at least 10 years long as education material.
 It has a very interesting video mode, where the upper part of the screen is for the bitmap screen, and the lower 4 lines are text lines, where the user can make commands.
 This reminds me to the Enterprise Graphics mode, where the same happens.

 My question ist, where the "graphics" screen with the 4 textline idea came from? Was it some kind of standard that time?

 Another question just to understand the environment, Mr. Tanner if you could answer it: During the developement time of the Enterprise Computer, were the Apple II computers available in the UK schools and companies? Did you use them?

I cannot remember seeing it on any other computers, but I also cannot remember where the idea came from! .

It made me think... did any mainframe terminals have status lines, as that was still a big influence in the early 1980s. I cannot find any evidence of this, but I came across this colour picture of a VT-52 terminal (wikipedia). Does the keyboard remind you of anything?

I remember there were not many games, but there was some, where during the TAPE loading screen there was a changing picture instead of static picture.
The one is maybe Tili-Toli game. The other was a triangle which was shrinking until it was a line and back. My version of Ninja Commando had this effect. (Maybe i mistaken the game).
